An "experienced parachutist" died when he landed badly on a skydive at a family open-air music festival.
Ryan Brown, 31, from Goole in East Yorkshire, suffered multiple injuries at the fundraising event at Bridlington Sports and Community Club last night.
Mr Brown took part in the parachute jump at 8.30pm but landed badly and officers were informed of the incident just after 9pm, a spokesman for Humberside Police said.
Mr Brown was airlifted to Scarborough General Hospital where he died as a result of his injuries.
Detective Sergeant Steve Shanks, of Bridlington CID, said: "Although there appears to be no suspicious circumstances surrounding Ryan's death, a thorough and full investigation will take place covering all the attendant circumstances and background to the incident. Our thoughts are with his family and friends.
"Ryan's death at this stage appears to be a tragic accident. He was an experienced parachutist."
One witness told BBC News that the skydiver was part of a team performing stunts at the family event.
The crowd, which included many children, saw Mr Brown land badly during one of the manoeuvres.
The British Parachuting Association has opened an investigation into his death and representatives are due to visit the scene of the accident this week.
A Humberside Police spokesman said a file is being prepared for the coroner and appealed for anyone who may have witnessed the incident to contact officers on 0845 6060222 quoting log number 847 21/08/2010.
