Three men were arrested in Kaikhali off VIP Road on Monday for allegedly siphoning off Rs 21 lakh from an ATM in New Town on May 30.
The men are part of the gang that had stolen over Rs 2 crore from at least 10 ATMs of a private bank in Calcutta last month, police said.
The men have been identified as Mohammed Vakil from Punjab, Sandeep Gupta alias Sonu and Amit Gupta alias Amrit who are from Delhi.
“The arrested men used to rent flats in different areas of the city and change their SIM cards every alternate day to avoid police tracking. They had even got fake Aadhaar cards made. We are trying to arrest other members of the gang,” the police said.
