A man attacked people in and around a library with a knife Saturday, killing a woman and injuring six other people in North Vancouver, British Columbia, authorities said.

The suspect is in custody, said Sgt. Frank Jang of the Integrated Homicide Investigation Team. Subject is in his early 20s and this is not his first interaction with the police.

Police still have no information on the assailant’s motives, according to Jang.

A witness, Steve Mossop, noted that he and a person he was with stopped in traffic when they saw a bloody woman who told them she had just been stabbed. They then saw several victims within 100 meters (yards) of each other, he added.

“There was a man, an older woman, a young woman, a mother – a mixed bag of people in the wrong place at the wrong time,” Mossop said.

“It seemed that he was only running in one direction and made a victim whoever he came across,” Mossop said in reference to the attacker.

On Twitter, Canada’s Minister of Public Safety Bill Blair said he was shocked and saddened by the incident, which he described as a “wild act of violence.”
