The four occupants of a vehicle that crashed into a tree late last night are now battling serious injuries.

On Tuesday night at approximately 11:50 p.m., first responders arrived at the scene of a single-vehicle collision.

When arriving in the  200 block of Dalhousie Drive, crews saw the vehicle had collided with the tree, requiring the Winnipeg Fire Paramedic Service's assistance to extract the occupants.

All four occupants were rushed to the hospital where they remain in critical condition. 

Police believe high rates of speed attributed to the crash.
