Jean-Pierre Veilleux said his first inkling that something was wrong was when he heard a loud smash from his neighbour's west-side Saskatoon home.

"My kids came up to me and said, 'Dad, somebody is trying to break into the neighbour's house,'" he said.

"Right away, I grabbed my bat."

According to police, a suspect had broken into the home on Lisgar Avenue around 8 a.m. CST and stabbed a female victim multiple times. Her injuries are not life threatening.

That's when Veilleux arrived.

"I hit him once in the head with the baseball bat, swung again and hit him in the arm."

Veilleux then chased the suspect out of the house, over a fence and down the alley. He caught him and subdued him, then called police using the suspect's own phone.

Police said the invasion does not appear to be random and that the suspect and victim knew each other. Police are still investigating.

The suspect's injuries are not life threatening.
