POLICE have received dozens of calls from people who were at a party with a Herefordshire skydiver the night before he plunged 13,000ft to his death.

Stephen Hilder died at Hibaldstow Airfield, North Lincolnshire, on Friday afternoon.

The cord on the 20-year-old's parachute had been deliberately cut, say Humberside Police detectives, who have launched a murder investigation.

Several people who were at a party at the skydiving centre with Stephen the night before his death and took video footage or photos have come forward.

Dozens of others who visited the centre the week Stephen was there have also contacted police.

"A number of calls have provided various new lines of inquiry and detectives will be looking more closely at these," said Det Supt Colin Andrews, of Humberside Police.

Stephen's family, from Stretton Sugwas, near Hereford, have released video footage of him doing a previous jump in the UK last April in a bid to assist the police investigation.

And police liaison officers have been in Herefordshire to meet Stephen's friends and family and build up a picture of his life.

A Humberside Police spokesperson also confirmed around 70 people who were at the airfield on the day of the jump have been given DNA tests.

Stephen was studying management and logistics at the Royal Military College of Science at Shrivenham, Wiltshire.
