MYSTERY surrounds the death of a personal fitness instructor who died when his car careered off a Worcester road and crashed into a concrete bollard.

Delton Horner, aged 32, of West Pathway, Harborne, Birmingham, was killed when his Ford Escort swerved off the road and smashed into the bollard on the A449 Kidderminster to Worcester Road on Wednesday, March 12.

Paramedics attempted to revive him but he died from shock and haemorrhage.

An inquest in Stourport-on-Severn on Tuesday heard that Mr Horner was 200 yards away from the Blackpole Road turning when the accident happened.

Judith Hargreaves, who was driving a car behind Mr Horner, described in a statement how she saw him swerve to the left, go up an embankment and hit the bollard.

"I couldn't believe what I had just seen. There were no other cars to force him off the road," she said in the statement.

The inquest heard that experts could find no reasons for the crash. The car was in working order and Mr Horner was healthy.

Worcestershire coroner Victor Round said the reasons for the crash would never be known.

"There could have been a wasp in the car or some other distraction and that evidence gets destroyed in the crash," said Mr Round.

"There is nothing to say he would wish to do himself harm and there was no suggestion that he was using a phone. We're lost."

He recorded a verdict of accidental death, saying that Mr Horner left the road for reasons never established.
