The Mumbai police have busted a Bihar-based illegal call centre whose operators duped people in the name of coronavirus, and arrested five persons, one of them a BTech graduate, and detained a minor who were part of the racket, an official said on Tuesday.

The cyber cell of the Mumbai police's crime branch unearthed the racket during an investigation into a complaint lodged by a city resident who was cheated, he said. Those apprehended were allegedly running the fake call centre and duping people by using the Covid-19 pandemic as bait, the official said.
