Mounties are seeking information on a Big River First Nation hit and run that led STARS to airlift an 11-year-old girl to Saskatoon hospital Sunday night.

Five youths were walking on the road on the reserve around 9 p.m. Sunday night when a four-door white car collided with the group and failed to stop, according to Big River RCMP.

The 11-year-old girl was seriously injured while four other kids were treated and released on scene.

Mounties say witnesses saw around six or seven people in the vehicle at the time of the collision.
