Toronto police are turning up the heat on the so-called "Mummy Bandit," a suspect alleged to have robbed nine banks in the downtown core over an eight-month period.

On April 15, police had released a picture of the bank robbery suspect, in a bid to identify him. At that time, Staff Inspector Mike Earl said that the suspect had used either a knife or a gun in "approximately" seven robberies since October 2013.

Earl said the suspect had worn disguises, including an occasion in which he wore a scarf "tightly wrapped around his face," leaving only his eyes visible. On another occasion, he wore makeup on his arms and face that gave him an appearance similar to the Joker — the comic book adversary of Batman.

Today, police released further images and a video of the suspect, which can be viewed at the top of this page, alleging that he has robbed an additional two banks since last month’s news conference.

One of those robberies occurred on April 22, at a bank in the Fort York Boulevard and Spadina Avenue area. Police allege the suspect went behind the counter, before producing a handgun and waving it around. He grabbed some money and fled.

On May 14, police allege the suspect robbed a bank in the College Street and Bathurst Street area. In this case, it is alleged that the suspect brandished a gun, went behind the counter and "threatened the victims" while demanding money. He fled the bank after receiving money.

The suspect is described as a 20-to-30-year-old white male, who is between 5'6" and 5'10".

Anyone with information is asked to contact investigators at 416-808-7350. Information can also be passed on anonymously through Crime Stoppers at 416-222-8477.

Over the past decade or so, bank robberies have been on a steep decline in Canada, including in the Greater Toronto Area.

Statistics from the Canadian Bankers Association indicate that there were 236 bank robberies in the GTA in 2000, while just 116 in 2012.

Earlier this year, Earl, the head of the hold-up squad, said that police have tended to solve 85 to 93 per cent of all annual Toronto bank robberies, in recent years.
