A 25-year-old man facing seven charges after a dangerous police chase in Saskatoon last month was handed nine additional charges Wednesday.

Timothy Gunn was charged with dangerous operation of a motor vehicle, possession of a stolen vehicle and assault with a weapon shortly after the June 25 incident. His new charges included assault on a police officer with a truck and wearing a disguise with intent to commit an indictable offence, as well as additional counts of driving causing bodily harm and five counts of failing to stop at the scene of an accident.

Gunn, who was wanted in Lloydminster in relation to an armed robbery last month, allegedly damaged four police cruisers and at least six civilian vehicles in the span of an hour.

He was wearing a bandana over his face during the chase, according to police.

The incident began just after 4:30 p.m. when police were called about a truck driving erratically around Avenue I and 19th Street.

Officers pursued the vehicle before the chase was called off at 8th Street and Lorne Avenue. The vehicle doubled back into the downtown area where the driver crashed into two vehicles while avoiding stop sticks deployed by police at Idylwyld Drive and 20th Street.

The truck continued to Avenue Q where it hit a police cruiser and was involved in three more collisions before moving towards a police officer who was trying to clear people from the sidewalk near Avenue Q and 24th Street, police said.

The officer pulled his gun and fired shots at the suspect vehicle before getting out of the way.

At Fairlight Drive another police cruiser was badly damaged and a third police vehicle was damaged when the officer rammed the truck to bring it to a stop at Circle Drive and 11th Street.

The driver tried to flee on foot but he was arrested with the help of a police dog. Police said the driver suffered injuries from the collisions and from the dog. He was not injured by the gunshots.

One civilian suffered non-life threatening injuries during the incident. No police officers were injured.

Gunn has since been ordered to undergo a three-day psychiatric assessment as he has a history of ADHD.
