Saskatoon police are investigating what prompted a 21-year-old man to jump from a City Park apartment building window Thursday morning.

Officers were called to the building on the 400 block of 4th Ave. N at around 7:30 a.m. CST.

They came across the injured man on the sidewalk.

He initially told officers that he'd been hit by a car. But police quickly figured out that he'd jumped from a window in the building.

They searched the suite but it was empty.

The man was taken to hospital with non-life-threatening injuries.
