Police have named a man who was murdered in North Yorkshire.
Mohammed Saleem Khan, 36, died in a road accident in Long Street in Easingwold early on Sunday morning. It was thought he died in the car crash but further investigations revealed he had been stabbed in the neck.
Police said the attack could be racially motivated and Mr Khan, who was orginally from Luton but was recently living in Birmingham, was delivering shower parts in North Yorkshire in a hired van.
Four people have been arrested as part of the investigation - a 26-year-old local man, and three other local people, a woman aged 20, and two men aged 21 and 25, were arrested on suspicion of assisting an offender.
Detective Chief Inspector Heather Pearson, from North Yorkshire Police, said: "I would like to speak to anyone who has any information that can help the investigation to come forward as soon as possible. If you saw or heard anything suspicious in the early hours of Sunday morning you may have information which is vital to our enquiries."
Anyone who can help officers with their enquiries should contact North Yorkshire Police on 101 - select option 2 - and ask for York CID.
