A Saskatoon man claims a simple honk sparked a road rage incident that saw him beaten in front of his wife and kids. Now, he says the family is is considering moving out of the city.

Last week, Robert Lorensen and his wife, daughter and son were waiting to advance at a green light, when he honked at the pickup in front of him to move ahead.

As footage from his dashboard-mounted camera shows, the pickup advanced, then braked, as the driver and Lorensen exchanged gestures.

Lorensen continued on his way, not realizing the pickup was following the family until he pulled into their driveway less than two minutes later. That's when Lorensen approached the pickup parked at the end of his driveway.

“It was fight or flight. I wasn’t running from my family, so I was fighting,” he says. “So I walked down to the vehicle and asked them what they wanted.”

Three men in the pickup got out and a fight ensued. A security camera at the front of the Lorensen's home captured parts of the violent confrontation, and showed his wife rushing their children into the house.

Lorensen says his head was smashed into the concrete, that he was kicked, and stabbed by what he believes was a four-inch screw. The fight ended when Lorensen's wife handed him a baseball bat.

The couple's five-year-old son, Hunter, witnessed part of the incident.

“He cries in his sleep since it happened, he screams in his sleep. He wakes up and grabs my arm and looks at it and is constantly concerned about me being stabbed to death,” he says.

Saskatoon police say they're investigating. No charges have been laid.

Lorensen says he and his family were planning to move to Vanscoy, Sask. in about three to four years, but they’ve now decided to move up that plan, worried that a similar incident could happen again.
