A policewoman has died 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 incident happened in Londonderry on Friday night.
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.
The Limavady Road remained closed at its junction with Glendermott Road and Clooney Terrace this morning while investigations are carried out.
The Northern Ireland Police Ombudsman's office has been informed.
Ulster Unionist member of the Northern Ireland Policing Board Ross Hussey said he was shocked and saddened by the officer's death.
"I would like to pass on my heartfelt sympathies to the family, friends and colleagues of this officer," he said.
"We can only imagine the pain that they must be feeling. I hope that her injured colleagues make a speedy recovery.
"This young woman's death in the line of duty serves to re-emphasise the dangers faced by the officers of the Police Service of Northern Ireland on a daily basis, as they put themselves in harm's way to protect the whole community. They deserve our full support."
