Those arrested were identified as Mohd. Miraz Alam (30), Shatrughan Ojha (30), Mohd. Jamal (34) and Anees (25), while four more members of the gang are still absconding and officials have been sent to Mumbai to nab them, police said.
Eleven fake voter ID cards, 13 PAN cards, 13 ATM cards, 17 cheque books, 15 passbooks, 14 mobile phones and six SIM cards have been seized from them, DCP (South) Ishwar Singh said.
"They would then stop taking calls of the victims. Like this, they have cheated people to the tune of around Rs 2.50 crore," he said.
To legitimise their act, the gang, with the help of a chartered accountant, floated a company, procured stamps and other documents, paid service tax and even filled up the requisite forms to avoid any sort of suspicion, the DCP said.
