The robbery took place at a branch of Bank of Baroda in the Juninagar area near Navi Mumbai at some time between Saturday and Sunday, a police officer told the Press Trust of India. A case has been registered and the police said they are probing the matter, which may have been planned over 5 months ago.
The bank staff discovered the robbery when they went to work on Monday morning and walked in to the locker room to find several vaults open.
The accused robbers, who are yet to be caught, had allegedly rented a shop next to the bank in May. Since then, they reportedly dug the tunnel which stretched to 25-feet, to reach the locker room of the Bank of Baroda branch. The accused allegedly opened 30 of the 225 lockers there, and walked away with valuables worth about Rs 40 lakh.
"A case under relevant sections of the IPC has been registered at the Sanpada police station," Navi Mumbai Police Commissioner Hemant Nagrale said, adding that a probe is on.
