Bill Murray of B&R Transport said the employee received a ticket Monday morning for talking on a cellphone while driving.
"He called on our two-way radio and said, 'Oh, I just got a cellphone ticket,'" Murray said.
"He went to pick up another couple of pickups that we gave him and then from there he went downtown and played smash-up derby."
Police said they would not release the name of a suspect until formal charges are laid.
It started Monday morning when a large moving truck blocked traffic on a busy downtown Winnipeg street outside police headquarters. A witness said the truck then started backing into a row of marked and unmarked police vehicles.
Tim Jaskow was standing on a nearby sidewalk when he heard a loud crunch and looked up to see the truck backing into the police cars three times.
"He hit the silver (car) ... then he pulled up again. Then he backed up again and went behind it to the next ones. Then he pulled up further yet and then he just floored it across ... at an angle into the ones behind," Jaskow said.
"The first time I saw it I thought he was making a delivery and made a mistake. Then, after that, I thought he was nuts."
The truck sped off. A dozen or so police cars followed.
The chase lasted almost two hours — first through city streets, then for another 80 kilometres westward on the Trans-Canada Highway beyond Portage la Prairie. That's where RCMP used a spike belt to stop the truck and the driver was arrested without incident.
"It's very brazen, especially during the day," said Sgt. Nick Paulet, who added he has never seen such a bold show of destruction steps away from the main entrance of police headquarters.
Murray said the driver has worked for B&R Transport for several months and is a good employee.
"He did his job and he did his job well."
