Explaining the modus operandi, Assistant Commissioner of Police (Crime) Mukund Hatote told a Thane court that "best performing" staffers were given reward of up to Rs 1 lakh by the operators of the racket for making US nationals cough up money.
The scam, which operated since 2013 through at least half a dozen call centres in Thane, targeted at least 15,000 US-based tax payers, who were allegedly conned by Indian tele-callers.
A drunken conversation tipped off Thane Crime Branch detectives to the unprecedented scam targeting unsuspecting Americans from call centres in Thane.
An industry of scamsters is operating in the guise of call centres in India.
