Toronto police have released video of a man they say has been impersonating a police officer in order to trick the elderly out of money.

Const. Tony Vella said police believe there have been 11 victims, all of them seniors, dating back to early June.

The most recent instance occurred on July 5, when the suspect followed an 83-year-old man into the lobby of a condominium in the Jarvis and King Streets area.

Police say the man followed the victim into the elevator and claimed he was an undercover police officer, demanding to see some identification.

The suspect then followed the victim into his residence.

Malcolm, 83, said he was tricked by a man impersonating a police officer. He said he had a friendly chat with the man, before he was accused of selling cocaine.

"He was so personable, he was so pleasant," said Malcolm, who did not want his last name published. "I was a casting director, and if I was casting for a crook he wouldn't get the part. He was just such an amiable fellow."

When Malcolm eventually asked to see the man's identification, he refused and left the scene.

On Wednesday, police released video footage of the suspect at the scene.

He is described as white, between 50 and 60 years of age and between six and six-foot-six in height. He has a heavy build with a potbelly, short grey hair and a moustache.

He was last seen wearing an army hat with a small brim, blue plaid short-sleeved shirt, dark pants and white shoes.

Last month, police said a 91-year-old man was loading his car with groceries on June 14 when a man approached, identified himself as an officer, and accused the victim of taking cocaine.

The victim was then asked to empty his pockets, at which time a quantity of money was stolen.

Later the same day, an 85-year-old man with a walker was approached near Queen Street East and Alton Avenue.

A man again identified himself as a police officer and demanded the man's identification. The victim turned his wallet over to the suspect, at which time a quantity of cash was removed before he fled the scene.

Police said the public should be aware that plainclothes officers will identify themselves verbally and present a police badge and warrant card.
