Aggravated Fraud in İzmir: Offence and Penalties (TCK 157-158)

Fraud is one of the most frequently encountered property offences in a commercially busy city such as İzmir, committed both by classic methods and through digital channels. In recent years the bulk of case files has centred on fraudulent websites, telephone calls in which the caller poses as a bank security officer or a public official, and wire transfers made by victims with their own hands. This article examines the basic elements of fraud (TCK 157), the aggravating circumstances that increase the sentence (TCK 158), the use of information systems and banking channels as a tool, the effect of effective remorse (TCK 168) on proceedings, the steps victims and suspects should take, and the competent court and Bayraklı Courthouse practice in İzmir. For the general framework of the offence you may also read our article on the offence of fraud and its penalties.

Elements of Fraud: Deceptive Conduct, Deception and Obtaining a Benefit (TCK 157)

TCK 157 defines fraud as deceiving a person through deceptive conduct and thereby obtaining a benefit for oneself or another to the detriment of that person or of a third party. This definition creates a chain of three links: first the deceptive conduct, then the mistaken belief it produces in the victim, and finally the loss of property flowing from that mistaken belief together with the benefit obtained by the perpetrator. If any link is broken, the offence does not arise; where the victim knew the truth from the outset and paid regardless, the element of deception is absent.

Because deceptive conduct is not defined by statute, it is assessed case by case. The test applied in judicial practice is whether the conduct goes beyond a simple lie and is objectively capable of deceiving: producing forged documents, creating a false corporate identity, or constructing a scenario that removes the victim's ability to verify the facts. The victim's age, education and circumstances also affect this assessment; a scheme that would deceive an elderly victim may not have the same effect on an experienced merchant. The offence can only be committed intentionally, the perpetrator acting in the knowledge that deception is being used to obtain an unlawful benefit. It is completed at the moment the benefit is actually obtained, a point that also matters for determining territorial jurisdiction.

The most contested boundary in practice lies between fraud and mere breach of contract. Not every person who fails to pay a debt or honour an undertaking is a fraudster; criminal liability requires that the perpetrator used deception at the very moment the relationship was formed and acted from the outset with the intention of not performing. This distinction is the threshold that determines whether the prosecutor issues a decision of non-prosecution in complaints arising from commercial relationships in İzmir.

Aggravating Circumstances (TCK 158)

TCK 158 provides for an increased sentence where fraud is committed using particular instruments or capacities. The circumstance most frequently encountered in practice is the use of information systems, or of banks or credit institutions, as a tool. The rationale is plain: payment infrastructures and digital systems that enjoy public trust dramatically amplify the perpetrator's capacity to deceive while reducing the victim's ability to verify. In the same way, using public institutions and organisations, professional bodies with public-institution status, political parties, foundations or associations as a tool constitutes an aggravating circumstance.

Other significant circumstances listed in the article include exploiting a person's religious beliefs and sentiments, taking advantage of a dangerous or difficult situation or of diminished perceptive capacity, the perpetrator posing as a public official or as an employee of a bank or credit institution, and commission of the offence in the course of commercial activity in the capacity of a merchant, a company director or a cooperative manager. Abuse by members of the liberal professions of the trust their profession confers, and commission of the offence by three or more persons together or within the framework of a criminal organisation, also fall within this scope. In a city with İzmir's trading volume, allegations of fraud committed in a merchant capacity arise particularly in supply, commission and advance-payment relationships. Since aggravating circumstances affect not only the sentence but also the competent court, the assessment of pre-trial detention and the limitation period, the classification set out in the indictment should be contested from the outset.

Cases in which the name of a public institution is used have increased markedly of late. Links embedded in text messages that appear to come from the tax office, the social security institution, a courier company or the e-government portal direct the victim to a counterfeit page where identity and banking details are entered. Use of an institution's name, logo or official-looking correspondence format may result in the act being treated as an aggravated form.

Fraud Committed Through Information Systems and Banks

A significant portion of the files reaching prosecutors in İzmir begins with a transfer the victim makes from their own banking application. The typical scenarios resemble one another: a fraudulent website imitating a genuine bank's interface, a spoofed call that displays the bank's call-centre number on the screen, one-time passwords requested under the pretext of identity verification, or bogus platforms promising investment or crypto returns. In such cases the victim is deceived through an information system and usually by means of banking infrastructure, so the act is assessed as aggravated fraud.

The critical distinction here is whether the victim, having been deceived, made the transfer personally. If the victim's will was steered by deception, the offence is fraud; if funds were moved entirely without the victim's knowledge or will by manipulating the system itself, the offence of obtaining an unlawful benefit through information systems may apply. Because the two classifications carry different consequences, account movements, login records and IP data must be read correctly from the start. Following the money is decisive in the investigation: successive transfers out of the recipient account, cash withdrawal points, transfers to crypto exchanges and third-party accounts used as intermediaries are all traced. For the technical dimension of the subject you may review our article on how cybercrimes are committed.

Tracking account movements serves not only to identify the perpetrator but also to see at which point the victim's loss can be halted. If the balance in the recipient account is blocked before the funds are withdrawn from an ATM or converted into crypto assets, the prospect of recovery improves considerably. Moreover, any dispute over liability between the bank and the victim may give rise to a separate civil claim independent of the criminal file.

Effective Remorse (TCK 168) and Restitution

TCK 168 regulates effective remorse for offences against property and applies to fraud as well. The logic of the provision is to encourage genuine restitution of the victim's loss. To benefit from it, the offence must be completed and the perpetrator must, showing remorse, fully remedy the victim's damage either by returning the property or by paying compensation. Partial payments are, as a rule, not sufficient; however, where partial restitution is made with the victim's consent, the reduction may be applied in proportion to the part remedied.

The rate of reduction depends on the stage at which restitution takes place: a broader reduction is available where the damage is remedied during the investigation, that is before the prosecution stage begins, while restitution made during trial but before judgment attracts a more limited reduction. Timing is therefore a strategic factor in itself for the suspect. One practical point deserves attention: payment must be documented as having actually reached the victim, since payments made without a bank receipt, a statement from the victim or a document filed with the court can give rise to dispute. For the victim, effective remorse may mean that the loss is recovered within the criminal file without pursuing a lengthy civil claim. Restitution does not, however, extinguish the offence; the public prosecution continues and the only consequence is a reduced sentence. It must also be stressed that no outcome can be guaranteed in any file and that the conditions for reduction are assessed by the court on the concrete facts.

Effective remorse should not be confused with mediation. Mediation is a separate mechanism that ends the criminal process when the parties reach agreement through a mediator; because effective remorse is specifically provided for restitution in fraud cases, the mediation route is not applied. An agreement with the victim therefore does not extinguish the case, it merely opens the way to arguing for a reduction under TCK 168.

The Process for Victims and Suspects

For the victim, the process begins with filing a complaint with the chief public prosecutor's office or the police. Although aggravated fraud is prosecuted ex officio, the victim knows the events best, so the content of the petition shapes the course of the file. A well-drafted petition sets out the chronology with times; it states clearly which number called, which web address the victim was directed to, and how much was sent to which IBAN, and it specifies the concrete measures requested, such as blocking the recipient accounts, obtaining call and IP records, and requesting bank camera footage. Transfer receipts, screenshots, message logs and any voice recordings should be annexed.

Tracing the money is time-sensitive. Calling the bank to request that the transaction be stopped the moment the transfer is noticed, and filing the complaint the same day, materially increases the prospect of seizure and return if a balance remains in the recipient account. The prosecutor may seek a seizure order over assets considered to be proceeds of the offence, and assets clearly established as belonging to the victim may be returned during the investigation. For the suspect, the process usually begins with a summons to give a statement. People who have allowed others to use their accounts may enter the file as suspects at the outset even where no intent exists. It is therefore important that the first statement be given with legal assistance so that account movements and communication records can be read in the defence's favour. On both sides of the process, working with an İzmir criminal lawyer ensures that evidence enters the file at the right time and in the right form.

It should be borne in mind that seizure and return procedures in the criminal file will not always cover the entire loss. Where no balance remains in the recipient account, the victim may need to bring a separate compensation claim under general provisions to recover the financial loss. The banking correspondence and expert findings obtained in the criminal proceedings provide a strong evidential foundation for such a claim.

Proceedings in İzmir: Competent Court and Bayraklı Courthouse

The division of jurisdiction is clear: cases concerning the basic form of fraud under TCK 157 are heard by criminal courts of first instance, while the aggravated forms regulated in TCK 158 fall within the jurisdiction of the assize court because of the upper limit of the prescribed sentence. This distinction has real consequences: proceedings before the assize court follow a heavier procedure in terms of mandatory defence counsel, the conduct of hearings and the scope of the evidential debate. As to territorial jurisdiction, the rule is the court of the place where the offence was committed; since fraud is completed when the benefit is obtained, the place where the benefit was secured is prominent. In practice, where the victim is in İzmir and the transfer was made from İzmir, the investigation begins at the İzmir Chief Public Prosecutor's Office.

In İzmir, investigation and trial activity is conducted at the İzmir Courthouse in Bayraklı. Once the complaint is filed with the chief prosecutor's office, the file is assigned to an investigation bureau; correspondence with banks and telecom operators, the obtaining of call and IP records, and victim and witness statements are completed at this stage. Identifying the suspect usually begins with establishing the holder of the recipient account and expands up the chain. When the indictment is accepted, the file proceeds to the assize court, where the victim may join the proceedings as an intervening party, submit evidence and pursue appeals. In serial fraud files with multiple victims across different provinces, applications to join cases may also arise. Throughout, regular follow-up of the file, timely submission of additional evidence and a properly argued legal classification are decisive for victim and suspect alike.

Because of the sentencing range it carries, aggravated fraud is an offence in which protective measures are frequently applied; judicial control measures may also be ordered instead of pre-trial detention. The length of proceedings varies with the number of victims, the speed at which banking and telecom correspondence is completed, and the scope of the expert examination. As every file is assessed on its own evidential structure, no undertaking as to outcome can be given in advance.
