An elderly woman from Khar has fallen victim to a fraudster posing as a CBI officer, losing Rs 8.8 lakh. The Khar police have registered a case and launched investigations into the matter, an official said on Sunday.

According to the police, the fraud began in August when the woman received a phone call from a person claiming to be one Vinay Kumar Chaibe, an officer from the CBI's Bangalore branch. The fraudster told her that a writ petition had been filed against her in the Bangalore court, alleging that fake bank accounts were opened in her name using her Aadhaar card, from which Rs 20 lakh had been taken by Naresh Goyal, who is under arrest for money laundering.
