Fraudster Who Fooled Even the Judge With AI-Fabricated Evidence... Prosecution Indicts Him in Custody After Supplementary Probe

The prosecution conducted its own supplementary investigation into a fraudster who had avoided detention by manipulating evidence with AI in a 300 million won–range investment scam, and has now brought him to trial in custody.

The Criminal Division 3 of the Busan District Prosecutors' Office Eastern Branch (Chief Prosecutor Kim Gun) announced on February 11 that it had indicted without detention a 27-year-old man, identified as A, whom the police had previously referred without arrest. He is accused of fraudulently obtaining approximately 320 million won in investment funds between August and October 2025 by claiming he would launch a cryptocurrency and cruise ship business and establish a medical center.

Before referring the case, the police had applied for an arrest warrant, but the court dismissed it. A submitted to the judge a forged bank balance certificate he had created on an AI image-generation platform. Although the account actually held only 23 won, he inflated the balance to more than 900 million won. A promised the victim that he would return the money.

The police forwarded the case to the prosecution without verifying the authenticity of the certificate. They had initially uncovered that A had posed as a doctor by generating a medical license with AI, yet failed to suspect that the bank balance certificate was also forged. A also manipulated cryptocurrency trading records and deposit transaction statements using AI to make it appear that he was a businessman holding tens of billions of won.

The prosecution traced the bank account. First, it confirmed through the bank's website, via the "Certificate Issuance Inquiry" service, that the certificate was fake. This service allows users to verify authenticity by entering the certificate's serial number. It does not, however, reveal the actual account balance. The prosecution then obtained a warrant to access the account records and arrested A two weeks after the case was referred.

In addition to charges of forging and using private documents, the prosecution also charged A with obstruction of the performance of official duties by fraudulent means for deceiving the judge, the prosecution, and the police.
