Toronto police say they are searching for a “clean-cut” bank robber that allegedly struck five financial institutions along Yonge Street within the last month.

Speaking to reporters at a news conference Tuesday, Staff Insp. Mike Earl said police believe the suspect, who has been dubbed the “Lunchtime Bandit,” held up five banks along Yonge Street from Davisville to Lawrence avenues between Nov. 21 and Dec. 17.

Police allege the suspect, who Earl described as “preppy” and “clean-cut,” walked into the banks posing as a customer and handed each teller a note, demanding cash and indicating he had a gun.

Earl said the suspect then fled the banks with an undisclosed amount of money.

The investigator added that the notes are “well-written” with “proper grammar.”

"Maybe he has never been in trouble before. Maybe he is an educated individual that is down and out and this is his only hope to get some type of money," Earl noted.

Four of the five robberies occurred between 12 p.m. and 1 p.m.

"Maybe he is on lunch break between 12 and 1 in that area. He could be a student," he added.

"He could have a job in the area."

Police suspect that the man is using the subway as his main mode of transportation.

Police have released photos of the suspect and are asking members of the public for help identifying him.

The suspect is described as a male in his early 20s with a medium build. He is believed to be between five-foot-ten and six-feet and police say the man is "well-dressed."

"We are hoping to give the tellers and the bank employees an early Christmas present by trying to get this preppy punk off the street before he goes on to commit further robberies," Earl added.

"It is not about the money with the hold-up squad with apprehending these individuals. It is the personal threat on the bank teller. Post-traumatic stress kicks in on some of these tellers. Some of them can’t return to work because of fear of the job."

Anyone with information about the case is asked to contact investigators at 416-808-7350 or Crime Stoppers anonymously at 416-222-TIPS (8477).
