Ten persons were arrested on Monday for allegedly running an illegal call centre from a building on Tiljala Road.

A police officer said: “The racketeers, posing as representatives of the Reliance Jio survey department, were calling people to inform them that their terrace had been chosen to set up a 5G mobile-tower, for which they would get Rs 20 lakh and a monthly rent of Rs 15,000 to Rs 25,000.”

The potential targets were allegedly asked to deposit Rs 10,799 if they wanted to let their terrace be used.

“Based on a specific tip off, a flat on the fourth floor of a building on Tiljala Road was raided from where 10 persons were arrested,” said an officer of south east division.

The police said they suspect the group of men had cheated several people to the tune of Rs 5 crore.

An officer said they carried out the verification of all the bank accounts where the victims had been depositing money and found that all the accounts had been opened with alleged fake documents.

“It is apparent that there are more people involved in the racket. The people who were making the calls were only at the front, but there are those who collected the phone numbers, opened bank accounts and withdrew cash from the ATMs. We are we are trying to locate them also,” said an officer of Karaya police station.
