A young man drowned after his car flipped onto its roof in a water-filled ditch at Haddiscoe.

Daniel Tubby, 29, was driving the Nissan Terrano and his friend Robert Bone was in the passenger seat at the time of the accident on the A143 at Haddiscoe last year.

A passing motorist dialled 999 after he saw steam rising from the ditch and heard someone shouting for help, an inquest heard yesterday.

Civil engineer Mr Tubby, of The Street, Earsham, near Bungay, was taken to the Norfolk and Norwich University Hospital (N&N) but died on July 25, 2015, hours after the crash.

He was not wearing a seatbelt and his injuries may have been less severe if he had been, crash investigator PC Jamie Hutchin said.

A post-mortem examination found that Mr Tubby was more than three times above the drink-drive alcohol limit and also had cocaine in his system.

Mr Bone, who had been wearing a seatbelt, survived.

In a written statement, he said he had known Mr Tubby for around a decade and he was his 'best mate'.

On the Saturday of the accident, he said they had met at the Three Tuns pub in Bungay, moved on to the Green Dragon then Mr Tubby drove them to The Bell pub in St Olaves.

They left the Bell, intending to 'go back to Bungay and go back to another pub' but crashed on the Haddiscoe bends.

Mr Bone said he remembered leaving The Bell, and his next memory was coming round in the car upside down in a ditch as the car filled with water, and he could not see his friend.

He added: 'I wish I had tried to stop him driving.'

The vehicle belonged to Mr Tubby's employer and was borrowed with permission, though his employer did not know it was being used other than for work use.

PC Hutchin said there were rolling tyre marks over the verge into the ditch, and there was no evidence that Mr Tubby had tried to steer round the bend.

'It's likely the amount of alcohol he had consumed with the amount of cocaine he had taken would have affected his judgment and affected his ability to control his vehicle,' he said.

The medical cause of death was given as drowning and multiple rib fractures due to a road traffic collision.

Assistant coroner David Osborne concluded that Mr Tubby died as the result of a road traffic collision.

He extended his sympathies to Mr Tubby's girlfriend and her father who attended the hearing.
