The behaviour of a gunman who violently attacked pub customers before terrifying one man with a pistol has been branded ‘absolutely abhorrent’ by detectives.

Richard Bowser flew into a rage when he had difficulty paying for his drinks while staying in a glamping pod at the Tan Hill Inn.

The 46-year-old assaulted staff and customers before being forced outside of the remote bar and returning to his where he had a pistol and shotgun stashed away.

However, his behaviour became more terrifying when he was confronted by the brother-in-law of one of his victims from inside the bar.

Teesside Crown Court heard how Bowser had been accused of pointing the revolver at the head of Lee Jackson before firing at him as he tried to hide away from him. Mr Jackson still has a bullet lodged in his arm after being shot by him.

He was cleared of two attempted murder charges - firing through the door and pointing the gun at Mr Jackson’s head – but was found guilty of wounding with intent.

Bowser was also found guilty of two charges pf possession of a firearm with intent to endanger life following the events on July 21 last year.

He was arrested at the venue, which lies on the Pennine Way in one of the remotest parts of the Yorkshire Dales, after he was Tasered by armed police.

Speaking after the conviction, Detective Superintendent Fran Naughton, of North Yorkshire Police, said: “The actions of Bowser that night were absolutely abhorrent and are likely to have a lasting effect on the victim and those who witnessed this horrendous ordeal.

“The other people caught up in this incident were innocently working or enjoying a summer’s evening out with family and friends. No-one should be subjected to fear and violence like they were that evening.

“Praise must go to the brave and quick-thinking members of staff who not only ensured the safety of their customers but have fully supported the police investigation which has resulted in this conviction.

“This was an isolated incident carried out by one man. However, the impact his actions have had on everyone involved that night, and the wider Tan Hill community are lasting. Tan Hill is a popular area in North Yorkshire, and we hope this incident does not stop people enjoying this special location.”

Bowser had already pleaded guilty to three counts of assault and two charges of possession of a prohibited weapon.

The 46-year-old, of Worcester Place, Bishop Auckland, County Durham, is expected to be sentenced next week at the same court.
