Winnipeg - A woman was sent to hospital Friday with serious injuries after a bomb exploded at a Winnipeg law firm.
Police said they were called to the Petersen King law office in south-central Winnipeg mid-morning.
Const. Eric Hofley said a police officer was not far from the office and was on the scene quickly to provide first aid.
He said the woman suffered injuries to her upper body.
"I am unaware of her condition at this point, but I can acknowledge the seriousness of her injuries,'' Hofley said.
Investigators did not know how the device ended up at the law firm, which several websites suggested specializes in family law.
"I am not sure how this device came to be in her possession, whether it was mailed or dropped off or something like that,'' Hofley said.
"At this point, it certainly does appear that however it came into her possession, it was an explosive device that was triggered inadvertently by this woman.''
There was some damage to a window in the building, but there were no reports of anyone else being hurt.
Police have taped off the building and blocked traffic around it while the bomb squad ensured there were no other devices.
"There's not an indication of that at this point, but of course our members are going to err on the side of caution.''
Police also partially evacuated another building downtown as a precaution.
Hofley didn't know what position the woman held at the firm.
Cathrine Gomes was working alone in Parkette grocery store about a block away from the explosion. She said police put up barricades near the store.
"What I see from inside is a lot of fire trucks, a lot of firemen and police all around our store,'' she said.
