A fake call centre was busted and seven persons were arrested for allegedly cheating UK nationals on Monday night.

The group would allegedly make internet calls to UK residents posing as representatives of an internet service provider from an office named “Bault Infotech” at Webel IT Park on Taratala Road.

“The men would allegedly seek permission for remote access to the victims’ mobile phones or laptops to check for glitches,” said an officer.

Once they gained access to a device, they would allegedly carry out online transactions from the victim’s account to multiple e-wallets and bank accounts, the police said.

A team of officers from the anti-rowdy squad of the detective department carried out the raid.

The seven have been sent to police custody till August 25.

Calcutta police have earlier arrested another gang from the same building in Taratala that was allegedly duping people abroad by posing as customer care officials of Amazon.
