Police said 71 debit cards were recovered from him, and three cases have been detected so far. The accused, identified as Francis Patrick Fernandes, was apprehended following a complaint lodged by a Borivali resident on February 7. According to the police, the complainant had gone to withdraw money from an ATM kiosk in Borivali when an unknown man approached him and offered assistance. Under the guise of helping him, the accused allegedly got the victim's PIN and swapped his ATM card with a duplicate one. The accused later withdrew money using the original card. The victim realised the fraud after receiving a transaction message and approached the police. A team led by senior inspector Jairaj Ranware examined CCTV footage and analysed technical evidence, which led them to Fernandes, police said. During interrogation, he allegedly confessed and was booked under section 318 of the Bharatiya Nyaya Sanhita....
