Saskatoon police said they made several arrests this week thanks to the air support unit (ASU).
Officers said they tried to make a traffic stop Wednesday around 2:45 a.m. near Alberta Avenue and 33rd Street, but the vehicle fled.
The ASU found the vehicle stopped in the 1600 block of Avenue C North, and saw the driver running on foot. The canine unit tracked the man and arrested him.
A 21-year-old man is charged with possession of a weapon for a dangerous purpose; carrying a concealed weapon; dangerous driving; evading police; and breach of conditions.
Police said they also tried to make a traffic stop on Monday night near Bedford Road and Avenue J North, and that vehicle also fled from officers.
The ASU tracked the vehicle leaving the city, and saw a shotgun being thrown from the vehicle.
The vehicle ran out of fuel and pulled into a farmyard at Township Road 784 and Range Road 3091, where four suspects were arrested.
Officers found the vehicle had been reported stolen earlier that morning.
A 36-year-old man is facing charges of dangerous driving; evading police; possession of stolen property over $5,000; possession of a firearm while prohibited; and breach of conditions.
A 32-year-old man, 29-year-old woman and a 22-year-old woman face charges of possession of stolen property over $5,000, with the 32-year-old man and 22-year-old woman also charged with breach of conditions.
