A young father is fighting for his life after falling from the top of a moving van in an apparent 'car surfing' stunt gone wrong.
Ben Dunbar, 26, suffered severe head injuries when he fell off the roof of a pal's Volkswagen Transporter van as he tried to ride on top of it.
He was rushed to Southampton General Hospital by helicopter where he remains in a coma.
The van's driver, an unidentified 27-year-old man from East Sussex, was arrested on suspicion of drink-driving, driving without due care and causing serious injury by dangerous driving. He was later released on bail.
One witness told the Daily Mail: "It appears he was hanging on the side of the van when it came round the corner and was flung off.
"The driver of the van was the first one to attend to him. He was on his phone.
"He was lying in the driveway of one of my neighbours.
"The paramedics were working on him for ages - they were working really hard, trying desperately to save him."
Medics worked for half an hour to stabilise Mr Dunbar at the scene before he was transferred to the air ambulance.
Fiona Peniston-Bird told the Mirror: "My son heard what sounded like a crash and then a man shouting for help. The ambulance arrived very quickly."
The force is also appealing for witnesses to Mr Dunbar's accident, as they try to piece together exactly what happened.
