MumbaiThe Mumbai crime branch, after busting a fake call centre racket at two offices in Malad and arresting 14 people on Thursday night, found that owners of the Malad call centre had previously worked at the Mira Road fake call centre busted by the Thane police in October 2016.Sources said the employees, who were not paid well at the Mira Road call centre, learnt how to cheat US citizens there and then started their own call centre in Malad to earn some quick money. “Some of these accused laid low after the Thane police raid and nearly four to five months ago they started the two call centres in Malad (West),” said a senior official of the crime branch.After questioning the first 13 people they arrested, the police nabbed one Amey Lokare for allegedly providing data of US citizens to the other suspects. Lokare, a computer engineer, is a resident of Malwani. The cops said he was in touch with Musir Shaikh, 28, one of the accused, and provided him the contacts.In the second office raided by the police, accused Zarar Haider, 24, who has also worked in the Mira Road call centre for seven years, used to get data from another person, who the police is trying to find.They used to ask the US citizens, who replied to their text messages, for their area code, find a gift shop in their area and ask them to purchase gift vouchers for tax settlement. After getting the voucher number, they used to give it to Abhishekh Dubey, 29, an accused, who used to encash it. He used to take 40% of the amount and give 60% to the call centre.Thane fake call centre: 298 arrested so farMeanwhile, the Thane police have so far arrested 298 people in connection with the fake call centre racket in Mira Road, which was busted last year.
