Murder detectives have arrested two men after the death of a woman found seriously injured in a car in Sussex.
Police and paramedics were called to the scene in Woodfield Road, Crawley, just after 1800 GMT on Tuesday.
They were unable to save the local woman, aged 27, who was declared dead 45 minutes later. Two Crawley men, aged 30 and 51, were arrested at the scene.
Police said the victim was violently attacked and officers were examining a knife found in a Volkswagen Passat.
Ch Insp Steve Curry, the commander for Crawley, said the victim and the two suspects were known to each other.
"There is no threat posed to the wider community by this sad occurrence," he said.
An area of Woodfield Road has been cordoned off as investigations continue.
Det Ch Insp Nigel Smith said: "The circumstances surrounding this lady's death are not entirely clear at this stage and we have forensic teams working on the car in which she was found, and a house in Woodfield Road.
"It would appear that she was the victim of a violent attack and we are examining a knife that was found in the car to establish whether this might have been used in the assault."
He said no-one else was currently being sought in connection with the woman's death.
