Former Bank Employee in Purwokerto Named Suspect in Document Forgery Case

The Banyumas City Police (Polresta) have named a former employee of Bank Mandiri Taspen Purwokerto Branch, identified by the initials N alias D (36), as a suspect in an alleged document forgery case. The falsified documents were used by the suspect to deceive a number of customers at the bank where he previously worked. Banyumas Police Chief, Senior Commissioner Petrus P. Silalahi, confirmed the suspect status after conducting a series of in-depth investigations. ‘Yes, he has been named a suspect for document forgery,’ said Petrus, accompanied by Criminal Investigation Unit Head Commissioner Ardi Kurniawan in Purwokerto on Tuesday. The investigation revealed that suspect N utilised a Sub Account Auto Grab Fund (SA AGF) form, which had been invalid since August 2025. This obsolete form was used to mislead customers in unofficial transactions. Criminal Investigation Unit Head Commissioner Ardi Kurniawan explained that the use of the form violated the bank’s internal regulations following an update to its core banking system. ‘Since the implementation of the new system, the form is no longer valid. However, the suspect allegedly kept and misused the revoked form sheets,’ Ardi stated. Based on forensic laboratory results, strong evidence of signature forgery was found on the documents. Suspect N admitted to acting alone since 2021 to meet personal needs and fund a lifestyle that included the desire to own a house and vehicles. In addition to the document forgery case reported by the bank, N alias D is also implicated in a fraud case involving a bogus investment scheme. Police estimate the total losses from this illegal investment scheme reached Rp25 billion, with more than 100 victims. The suspect is charged with multiple articles, and investigators are currently developing the case towards money laundering offences while coordinating with the Purwokerto District Attorney’s Office to complete the case files. Corporate Secretary of PT Bank Mandiri Taspen, Tulus P. Hutabarat, stressed that this case was the action of an individual and not a fictitious credit issue within the company. He confirmed that all official credit disbursements had followed proper procedures. The Purwokerto Financial Services Authority (OJK) is also investigating the fraudulent investment scheme involving the former employee. Banyumas Police are focusing on asset recovery for the victims of the bogus investment scheme, which is valued at Rp25 billion, through the money laundering investigation.
