A policewoman has been killed in a road crash involving a suspected stolen vehicle in Northern Ireland.

The 27-year-old officer was travelling in a police car on routine patrol when the fatal incident happened in Londonderry at around 3.40am on Saturday morning.

Two other officers in the patrol car sustained non-serious injuries.

Police are hunting for two males that made off from the scene on the Limavady Road in the direction of the Ebrington area.

Stormont Justice Minister David Ford said his thoughts were with the policewoman's relatives and the injured officers.

"I was shocked to hear of this tragic incident which resulted in the death of a police constable who was carrying out her duties serving the community in the middle of the night," he said.

"My thoughts and prayers are with her family at this time.

"I also send my best wishes to the two officers injured in this incident for a speedy and full recovery. It is hard to imagine how they, and indeed the wider PSNI family, are feeling."

The Northern Ireland Police Ombudsman's office has been informed.

The scene of the crash, on the Limavady Road at its junction with Glendermott Road and Clooney Terrace, has been closed while investigations are carried out.
