Thieves in the western Indian city of Mumbai robbed a government-owned bank after gaining access via a 25ft (8m) tunnel that they dug over four months.
The police told the BBC that cash and jewellery were stolen but the value of the haul is yet to be determined.
Authorities believe the group rented a space next to the Bank of Baroda so they could dig the tunnel.
They are said to have run a grocery shop on the premises to provide cover for their activities.
