Lethbridge Regional Police are investigating a hit-and-run injury collision that occurred during the early morning hours Sunday.

On Jan. 26, 2014 at approximately 2:49 a.m. a passerby contacted police after observing an injured male lying in the northbound lanes of Stafford Drive on the bridge deck. Upon arrival police located a 45-year-old male cyclist who appeared to be the victim of a hit and run collision. The male was initially transported to Chinook Regional Hospital with life-threatening injuries and later transferred to Calgary Foothills Hospital. He remains in Foothills Hospital in critical condition.

Police have released a photo from a nearby surveillance camera:

That's some pretty horrible potato camera quality, but at least it is something. Any guesses on what the vehicle in question might be?
