Another attempted theft of a bank night deposit box is being investigated by OPP.

This time it happened Monday at a Bank of Montreal branch in Thorndale.

OPP say suspects attempted to remove the box by using a vehicle.

They say the suspects were successful in removing the cover but the box didn't budge and they left empty handed.

OPP say they are aware of similar incidents in London and are investigating to see if there is any link.

Last month, two night deposit boxes were removed from London banks and an ATM machine was taken from a gas bar.
