Calgary police are looking for a self-proclaimed white supremacist and a teenager suspected of leaving explosive devices outside an apartment unit that were later detonated in a nearby parking lot.

Police have issued warrants for the arrest of Kyle Robert McKee, 24, and a 17-year-old male who cannot be identified under the Youth Criminal Justice Act.

They are wanted on charges of attempted murder; possessing, making or controlling explosives; and possessing a weapon or an imitation for a dangerous purpose.

McKee is linked to a white supremacist group in Calgary, but investigators said they don't believe the targeted attack was a hate crime.

"It's not really a concern who they're linked to," Staff Sgt. Keith Cain said Monday. "Anyone using a bomb is a serious concern for us and obviously we want to locate these persons and get them under arrest, or in custody, as soon as possible.

Early Saturday, police responded to reports of what sounded like gunshots in the 5300 block of Rundlehorn Drive N.E.

A resident in a ground-floor unit of an apartment building heard a noise outside and found two homemade bombs outside his patio door, Cain said. The man threw the devices into the parking lot, where they exploded.

"If he hadn't had thrown it away, he could have been injured inside, but if he had picked it up three or four seconds later, he could have been killed or injured throwing it away," duty Insp. Frank Reuser said Saturday. "So it's one of those situations where you're damned if you do and damned if you don't."

A vehicle was damaged, but no one was hurt.

Links to white supremacist group

McKee is believed to have helped found the Aryan Guard in Calgary, a white supremacist group that has organized marches in the city, including one in 2008 protesting the right of Muslim women to cover their faces while voting.

In March, members of the group marching for "White Pride World Wide Day" violently clashed in downtown Calgary with anti-racism protesters marking the International Day to Eliminate Racial Discrimination.

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."

"Ideally, we'd like to see it eventually turn into a fairly mainstream thing. You just get your average joe out there saying, 'I'm proud to be white,'" McKee told the newspaper at the time.

The neo-Nazi group made headlines in the summer of 2008 when it posted an offer in an online forum to help pay the rent of new members willing to relocate to Calgary.

In September 2006, McKee was charged with assault with a weapon and possession of a weapon or imitation for a dangerous purpose during an altercation in downtown Calgary where a man was hit with a wooden club, and another was stabbed.

Despite McKee's history, police said they don't believe Saturday's bomb attacks were a hate crime or related to gangs.

"The victims in this case know the offenders and share similar beliefs and values," police said in a news release issued Monday.

McKee is described as white with a slim build, blue eyes and a shaved head. He is five feet nine inches tall and 140 pounds, police said.
