The Canadian Bankers Association (CBA) is offering $50,000 for any information that leads to an arrest after a series of armed bank robberies in the GTA.

Staff Insp. Mike Earl said Thursday there have been at least eight brazen daytime robberies since June 1 at chartered banks in Toronto, Mississauga, Vaughan and Brampton.

In each case, there’s at least two young masked men who enter the bank, brandishing handguns and vaulting over the counter to steal cash but not before terrorizing the tellers and customers, including children and the elderly.

“These individuals are terrorizing the banking community and we need to put a stop to it,” Earl said at Toronto police headquarters.

Earl said he’s concerned by the escalation of violence in these robberies as the suspects have been pistol-whipping tellers, and pushing and slapping them. In one instance the robbers actually grabbed a teller in a choke hold while demanding their money, he added.

CBA’s director of security Bill Crate said, “People are being traumatized and people are being injured and we’re quite concerned about the escalation of violence that’s occurring.”

He hopes the $50,000 reward will lead to tips that will allow police to catch the thieves.

Police also released photos and some video of the suspects entering the banks in hopes of getting leads from the public.
