Patna: A retired Army soldier from Patna was allegedly duped of Rs 3.3 lakh after cyber fraudsters kept him under a 10-day “digital arrest” by falsely linking him to a Rs 6.8-crore fraud. The ordeal allegedly left him so traumatised that he later attempted suicide. The case came to light on Thursday.According to police, the fraudsters told the Mahendru resident that a bank account opened in his name at Delhi’s Chandni Chowk branch was linked to suspicious transactions worth Rs 6.8 crore. When he denied having such an account, the call was transferred to another person claiming to be a police officer.The callers accused him of helping criminals and threatened him with legal action. To make their claims appear genuine, they sent photographs of his house, appeared in police uniforms during video calls and even allegedly sent a person to his residence, convincing him that he was under surveillance.Fearing arrest and eager to prove his innocence, the retired soldier transferred Rs 3.3 lakh through RTGS to an account specified by the fraudsters.Following his complaint, the cyber police registered a case. Patna cyber DSP Nitish Chandra Dhariya on Thursday, said, “An investigation is underway.”Police said in his complaint, the retired man said he remained confined to his home for 17 days after the incident and even attempted suicide due to mental distress.The police have appealed to people not to trust unknown callers claiming to be police or enforcement officials and said no agency carries out investigations through “digital arrest”.
