Police say they have arrested a man they believe was attacking people at ATMs around the city.

The 31-year-old man is now facing 14 charges including robbery, aggravated assault and possession of a weapon dangerous to the public.

Officers said the most recent attack happened around 1 a.m. on Sunday, just 30 minutes before the suspect was arrested.

That victim was assaulted with a weapon after entering his pin number in an ATM on 108 Street and 82 Avenue.

“All three complainants in the personal robberies were struck on the head with what they described as either a baton or some type of a pipe,” Staff Sgt. Steven Chwok explained.

The victim was taken to hospital with serious injuries.

The other two attacks occurred in Beverly, one on Monday and the other on Wednesday.

Both of those victims also ended up with serious injuries.

The news has many Edmontonians reluctant to use the automated bank machines.

“I wouldn't come after dark, definitely not,” Roger Steele told CTV News.

“It seems that's when the assaults would happen so I'd come during the day.”

Mallory Foreman said she always banks in numbers.

“I just bring a group of friends mainly,” she said.

“I just be aware that people are like that out there and keep distance from certain people,” Foreman added.

Police suggest being cautious when using the machines.

“Make sure that things are safe.  See if there is somebody sitting in their vehicle watching, anything suspicious perhaps it's not the time to go to that ATM,” Staff Sgt. Chwok advised.

Police say they arrested the suspect after he was found in a suspicious vehicle at Capilano mall.

“They ran the plate on that vehicle it was listed as stolen and the suspect was taken into custody without incident,” Staff Sgt. Chwok said.

It was after he was behind bars they realized the extent of his crimes.

Official charges are expected to be laid against the suspect on Monday.
