A self-proclaimed white supremacist wanted in connection with a Calgary homemade bomb attack has been arrested in Winnipeg following a two-hour standoff with police.

Police, acting on a tip from the public, arrested Kyle Robert McKee, 24, on Wednesday at 12:30 a.m.

"He's a suspect in a very violent act," said Calgary police Staff Sgt. Keith Cain on Wednesday. "We believe it was a targeted attack, but nonetheless, it was a violent act, so we were very interested in locating him and getting him in custody."

McKee, who once described himself as a member of the now defunct Aryan Guard, faces several charges related to a Nov. 21 incident in Calgary.

Calgary police said the attack wasn't a hate crime, but a "personal vendetta between two individuals."

A resident in a ground-floor apartment in northeast Calgary found two homemade bombs near his patio door, police said. The man threw the devices into the parking lot, where they exploded. A vehicle was damaged, but no one was hurt.

McKee is believed to have helped found the Aryan Guard in Calgary, a white supremacist group that has organized marches in the city. In an interview with the Calgary Herald, McKee identified himself as a member of the Aryan Guard and explained that the group was simply trying to "celebrate white pride."

Shortly after the Nov. 21 attack, a message on the Aryan Guard's website said the group had disbanded due to the "the rash actions of so few."

Spotted in Sask.

A few days later, police in Saskatchewan said McKee was spotted behind the wheel of his own truck, which was parked on a gravel road south of Regina.

RCMP noticed the parked vehicle and decided to check things out. McKee gave the officer his name and produced an Alberta's driver's licence. However, as the officer was walking back to his vehicle to run a name check, McKee drove away.

McKee is the last person wanted in connection with the bomb attack. Cain said he expected McKee to be transferred back to Calgary within the week.

Police arrested a 17-year-old Calgary youth after he stepped off the bus in Portage, Man.

Both face charges of attempted murder, possessing, making or controlling explosives, and possessing a weapon or an imitation for a dangerous purpose.
