RCMP release photos of suspects in explosion at B.C. cabinet minister's office

Police say an explosion that blew open the door of a British Columbia cabinet minister's constituency office in North Vancouver came from an "unsophisticated" homemade device.

Cpl. Mansoor Sahak with the North Vancouver RCMP said the device was likely a number of bear bangers or fireworks taped together and lit by a fuse. 

The explosive went off just after 4 a.m. outside the office of Infrastructure Minister Bowinn Ma on June 27. 

Police have released photos, hoping the public will recognize the two male suspects.

One is described as a white man with short, balding hair, a stocky build, wearing a black jacket, dark T-shirt and blue jeans.

The other suspect is described as a white man with a slender build who was wearing a long, blond wig and a dark hoodie.

There were two explosions in the area near the same time, and Sahak said they believe the two men were also responsible for damaging a street sign earlier that morning. 

He said the motive for the attack is still unknown, but police don't believe they intended to hurt anyone. For now, police say they are looking at recommending potential charges of mischief.
