An 84-year-old woman died Thursday morning in a collision involving an on-duty Edmonton police officer driving an unmarked car.

The crash occurred about 10:36 a.m. near 75th Street and 76th Avenue. The constable, a six-year veteran of the force, was taken to hospital with injuries not believed to be life threatening.  He works with the surveillance unit of southeast division.

The Alberta Serious Incident Response Team (ASIRT) was been called in to investigate by Edmonton Police Chief Rod Knecht.

"You can tell by looking at the collision, it was a catastrophic collision that resulted in serious injuries to the police officer and a death," said ASIRT executive director Clif Purvis.

ASIRT will be assisted in the investigation by an expert collision analyst from the RCMP.

While several people witnessed the crash, Purvis says ASIRT would like to hear from others who may have seen what happened.

Purvis says the investigation will look at whether the police vehicle was involved in a pursuit at the time of the crash.

Knecht said he is planning to meet with the woman's family as soon as possible.

"So I can personally express my condolences on behalf of the Edmonton Police Service and myself," he said.

Knecht planned to visit the injured officer in hospital to provide support to him and his family.
