Toronto police are searching for three suspects wanted in a series of 11 separate bank hold-ups: Bubbles, Whiskers and the notorious Tunnel Rat.

The suspects, who are not believed to be working together, were given their monikers by police after the spate of bank robberies from last year.

Officials are now asking for help in identifying the alleged robbers.

Eight of the reported hold-ups were allegedly committed by the “Tunnel Rat bandit,” who earned his nickname for fleeing to the subway after the alleged crimes.

Tunnel Rat allegedly demanded money from bank tellers using a note and indicated that he was armed, police said. Afterwards, he fled to a nearby TTC station.

Police say that four of Tunnel Rat’s crimes were along the Danforth subway line. The alleged hold-ups occurred between Jan. 6 and March 11.

A $10,000 reward has been offered by the Canadian Bankers Association for any information leading to the suspect’s arrest.

Tunnel Rat is described as a white man in his 30s with dark hair and standing about 6’0”. Police say he wore a disguise of a baseball hat, glasses, a scarf and gloves.

Two alleged hold-ups were committed by a suspect dubbed “Whiskers,” a white male between 23 and 30 years old who police describe as having a “well-trimmed moustache and beard.”

Police say the first alleged hold-up occurred on May 7 at a bank near Dupont Street and Symington Avenue. The suspect allegedly handed the bank teller a handwritten note demanding money and kept his hand in his pocket, “indicating he may have had a weapon,” police said.

After taking the cash, Whiskers fled the scene in a taxi, police said.

Authorities allege the suspect was also involved in a similar incident on Oct. 19 at a bank in the York region near Steeles Avenue West and Bathurst Street, police said.

In a security image from one of the alleged hold-ups, Whiskers is seen wearing dark sunglasses, a toque, gloves, a dark pea coat and blue jeans.

The third suspect, Bubbles, was allegedly involved in a hold-up on March 4 at a bank near Dundas Street West and Bay Street.

The suspect approached a teller with an envelope demanding cash, police say, and then threatened to start shooting.

The suspect was then given money and fled the bank.

Bubbles is described as an unshaven black male between 30 and 40 years old. Security images from the incident show him wearing plastic-framed glasses, a black jacket and a toque during the incident.
