A young driver killed in a car crash had drunk alcohol and taken drugs before his death, an inquest heard today,

Bradley Wells died after his white Vauxhall Astra SRI left the C110 at Great Cressingham, near the junction with the A1065, and crashed into a field before flipping over.

The 24-year-old, of Jubilee Court, in Pentney near King's Lynn, was pronounced dead at the scene in the early hours of November 19 last year.

A postmortem examination revealed the cause of death as multiple injuries as a result of a road traffic collision.

A toxicology report also revealed alcohol and traces of cannabis and cocaine in Mr Wells' body. It was also suggested he may have been a regular cannabis user.

Graham Garrod was the first person on the scene after the crash at around 11.40pm on November 18.

Speaking at today's inquest at King's Lynn, he said: 'I was driving past the field on my way home from Swaffham along the A1065 and I caught a glimpse of what I thought looked like ambers in the field.

'I travelled a bit further up the road before turning back and going back to the field where I saw a car on its roof and what I though were ambers were actually hazard lights.'

Craig Peters told today's hearing he had enjoyed a drink with the 24-year-old in the Windmill pub in Great Cressingham a few hours before his death.

He said: 'He arrived at the same time as us which was about 8.40pm and he left before us, by himself, at 9.45pm. He hadn't had a lot to drink and I didn't see him take any substances.

He added: ''I thought he was going home because he said he was going to Amsterdam the next day and had to pack.'

Police inspector Alexander Bucher also told today's hearing that Mr Wells had been trapped underneath his vehicle and was pulled clear by the first paramedic on the scene.

He added: 'There is no evidence there were any other vehicles involved and there were no witnesses to the incident.'

PC Wendy Frary, collision investigator at Norfolk Police, told the court there were no mechanical defects with the Vauxhall Astra.

She also said she believed Mr Wells had not been wearing his seatbelt at the time of crash and that he had drunk two pints of Guinness in the pub.

She added: 'The reason why he failed to join the A1065 is unclear and I'm unable to provide an explanation for this. However the presence of alcohol and drugs in system may have had an affect on his driving ability.'

Coroner William Armstrong recorded a verdict of death as a result of a road traffic collision.

He added: 'Bradley was not wearing a seatbelt which is a matter of regret. There is also evidence he had both cocaine and cannabis in his system. There is evidence it's becoming increasingly the case that drugs are a factor in road traffic collisions.

'It seems therefore reasonable to infer the drugs he had taken impaired his ability to drive.'
