A 17-year-old boy has been arrested on suspicion of murder after a man was kicked to death by a gang in an Oxfordshire town.
The victim, who is thought to be in his early 40s, was knocked to the ground and kicked in the head on Greys Road in Henley-on-Thames in the early hours.
Thames Valley Police said he died later from "very severe" injuries.
Officers are hunting a gang of four or five men, who may have been carrying pizza boxes.
A post-mortem examination will be carried out later.
A shopkeeper said a CCTV camera is trained on the spot where the attack happened.
He added: "It happens in every town now on a Friday night. Henley is no different."
Taxi drivers at a nearby cab firm said they had been asked to help provide first aid to the man.
Det Ch Insp Pete Dowling said: "This is being treated as a murder inquiry and I would ask that anyone who witnessed the incident or who has any information contact me as soon as possible.
"While there is no suggestion at this stage that any weapons were involved, the attack on this man was extremely severe, and involved him being punched and kicked in the head.
"The only descriptions of the offenders are that they are white, all male and may have been carrying pizza boxes from a nearby takeaway.
"I would ask that anyone who witnessed the incident or who has any information contact me as soon as possible."
A section of Greys Road, including the car park, was closed while an investigation of the scene was carried out.
