Quebec man arrested after chainsaw used to threaten family

A 37-year-old man has been arrested in Quebecafter a family in a car was threatened with a chainsaw, in an incident captured on video by a "terrorized" mother of two.

The man was arrested Monday morning bypolice inSaint-Jrme, after a video of the alleged incident Sunday around 7 p.m. ET went viral on social media.

The car's passenger, Karine Cyr, recorded the confrontation with her cellphone, andposted iton her Facebook page. Itshows a man approaching the vehicle, swearing and revving a chainsaw.

Children inside the car can be heard crying.

"In the heat of the moment, I kept filming.... As a mother, I got very angry. I said, 'Before threatening my children, come and see me,'" Cyr told CBC Montreal.

The man ultimately left and went back to his vehicle.

"I think the man noticed that, first of all, I caught it all on video, and he could see on my face that I was terrorized and he saw me call the police."

Cyr said she and her family, who live inL'piphanie, Que.,were on vacation. She was in the car with her husband, AlexandreHermenier,who was driving, and their two children were in the backseat.

Cyr said the driver cut them off and was driving erratically, so her husbandfollowed the vehicle to get the licence plate number and tell police where the manwas going. They ended up on a dead-end roadand Hermenier parked his car, blocking the other vehicle from leaving.Cyr said that's when the driver got out of his car and threatened them with a chainsaw.

"It was a terrifying situation," Hermenier said.

The video has been online for less than a day, and by Monday evening had more than 600,000 hits.

Cyr said that, in hindsight, she would have handled the situation differently.

"Everyone will react differently, but I would like to say that if you see dangerous driving, do not follow the driver the mistake that we made with two children in the back seat. We regret it tremendously. If it happens to you, pull over and just call police."

Police say the man could face several charges.

"He will face charges of assault with a weapon for starters ... and he could face more charges," said spokesman Robin Pouliot.

The manis expected to appear at the Saint-Jrme courthouse Tuesday morning.
