PUNE: A 71-year-old retired central govt officer has lodged a complaint with the Vishrantwadi police, alleging that online fraudsters posing as senior Karnataka police and CBI officers threatened to arrest him in a child trafficking case and cheated him of Rs 22 lakh between Oct 5 and 15 this year.“The retired govt officer was at home when he received a video call from the suspects, who posed as Karnataka police officials. They claimed to be investigating a child trafficking case and said his phone number had been linked to the crime,” senior inspector Rajendra Panhale of the Vishrantwadi police station told TOI.Panhale said the suspects further claimed that the case was being jointly investigated by the Karnataka police and the CBI, as the complainant and others were allegedly involved in child trafficking across multiple states.“They threatened to arrest him in the case and obtained details of his bank accounts and Aadhaar card. They continued to threaten him with arrest through video calls, claiming that his arrest would bring disrepute to him and his family,” he said.“Later, they offered to help him settle the case in exchange for money.
