Emergency crews were called to the scene of a serious crash in the city’s southeast on Thursday morning that sent four people to hospital.

Police were alerted to a suspicious vehicle in a parking lot in the Douglasdale area at about 11:30 a.m. and witnesses told officers that the vehicle left the lot at a high rate of speed along 130 Avenue S.E.

Investigators believe a CPS member, in a marked unit, tried to pull the truck over, but the truck fled and the officer disengaged.

The truck later sped through a red light at an intersection at 46 Street and T-boned a car and then hit another vehicle that had been waiting to turn.

The male driver of the truck and the female passenger both ran from the scene on foot. The man was apprehended a short distance away but the woman was able to get way and has not yet been located.

EMS says two men from the car sustained multiple traumatic injuries.

The driver, a man in his 20s, was taken to Foothills Hospital in serious potentially life threatening condition. The second man, in his early 30s, was a passenger in the vehicle and was transported in stable and non-life threatening condition.

Both have since been upgraded to stable condition.

EMS returned to the scene about an hour later to assess two more people who were in another vehicle. Two women in their 50s was taken to South Health Campus with soft tissue injuries and are in stable condition.

The Alberta Serious Incident Response Team, ASIRT, is now investigating the circumstances surrounding the crash and is asking anyone who witnessed the collision to call them at 403-592-4306403-592-4306.
