Police were hunting a trio of would-be robbers in Mississauga last night, after they tried unsuccessfully to hold up an armoured car outside a bank.

It was just after 9:30 p.m. when a pair of armed guards were working outside a TD Bank on Southdown Road, just north of Royal Windsor Drive and immediately adjacent to the entrance for the Clarkson GO Train Station.

They were approached by three men, who sources said were armed with a pellet gun, but the guards weren't having any of it.
