A man who is accused of a growing number of bank robberies in two Canadian cities has struck again in Toronto, police say.

Toronto police responded to an armed robbery on Wednesday afternoon at a downtown BMO branch located near King and Bay streets.

After the robbery, police had said the suspect was a bald, black male with some white hair showing, believed to be 35 to 40 years old

He was wearing a blue T-shirt with the word "Winnipeg" written on the front, and was carrying a black handgun.

Police believe that man was Corey Richardson, a 44-year-old man who is now wanted on 13 counts of robbery.

It is alleged that Richardson is responsible for two bank robberies in Winnipeg and 11 more in Toronto.

The robberies police allege he is responsible for have followed a typical pattern of being downtown, near the subway in high-traffic areas.

Just days ago, the Canadian Bankers Association announced a $10,000 reward for anyone who could provide information leading to Richardson’s arrest and conviction.

Malcolm Chivers, the organization’s manager of security and intelligence, said that someone must know where Richardson is and that information can help police apprehend him.

"Definitely we want somebody to do the right thing," Chivers said.

Police say that Richardson is considered dangerous and should not be approached.

If he is spotted, members of the public should call 911, police say.
