An inquest into the death of TT ace David Jefferies is set to be resumed in the Isle of Man next week.

The Baildon biker was killed in the races on the island in May when his 1,000cc GSXR Suzuki crashed.

The 30-year-old died instantly during the second lap of a practice session on the course, for which he was lap record holder.

He suffered multiple injuries and died at the scene when his bike collided with a telegraph pole.

Isle of Man coroner Michael Moyle opened the inquest in June.

It was adjourned after advocate Peter Saunders, who appeared on behalf of TAS Suzuki, the team Mr Jefferies rode for, said he wanted four riders who were at the scene and a rider who followed a bike which broke down further along the course to be interviewed.

He told the inquest the witness statements that could show there was oil on the course were not gathered from the riders.

There was speculation that a vehicle had pulled on to the circuit just before the accident but Mr Moyle confirmed at the inquest's opening that the theory of a third party coming on to the circuit could be discounted.

Before adjourning the case to allow time for Mr Saunders to gather his evidence, the coroner read out statements from two German TT fans - Martin Holtkamp and Berntd Preiss - who watched the practice session from the Crosby Post Office, near the crash scene.

Neither of them saw Mr Jefferies actually crash.

Stars from the world of motorcycling were among hundreds of mourners who went to Mr Jefferies' funeral at St Peter's Church in Shipley in June.

A spokesman for the Isle of Man Coroner's Office said the dates for the resumption of the inquest had been provisionally set for August 20 and 21.
