The Lucknow cyber crime branch registered a complaint on Wednesday after a doctor was duped of Rs 2.8 crores by fraudsters posing as Central Bureau of Investigation (CBI) and Telecom Regulatory Authority of India (TRAI) officers.

The victim, identified as Ruchika Tandon, was posted at the Sanjay Gandhi Post Graduate Institute of Medical Sciences in Lucknow and was kept under 'digital arrest' by the fraudsters for six days by involving her name in a fake money laundering case. The money was transferred to seven accounts in those six days.
