A violent thug who stabbed a man in a row over loud music has been jailed for five years.

The High Court in Glasgow heard that Sean Wilson, 21, left victim Michael Muir needing emergency surgery to stem the bleeding from stab wounds to his back and a punctured lung.

The attack took place in Huntersfield Road, Gorebridge, Midlothian, on December 3 last year.

Police found Mr Muir lying, groaning, with Wilson trying to staunch the blood with a towel. Wilson confessed to police he had stabbed Mr Muir.

During a trial Wilson claimed he stabbed Mr Muir because he had indecently assaulted a girl, but, Mr Muir dismissed the claim as "nonsense."

Wilson, of Gorebridge, was cleared of attempting to murder Mr Muir. However, a jury found him guilty of a reduced charge of assaulting Mr Muir to the danger of his life.

In evidence, Mr Muir agreed he might have had a dart in his hand when he went to complain about the music blasting from the hostel room in Huntersfield Road.

He said Wilson, a guest in the room, started giving him abuse, adding: "I had a bit of a shouting match with him."

Mr Muir continued: "The next thing I realised there was a knife. I put my hands up to protect my face and felt a sharp sensation in the back - twice."

Wilson has previous convictions for serious assault, using a bottle as a weapon, and for culpable and reckless conduct involving a petrol bomb.

Temporary judge Michael O'Grady told Wilson: "It is clear that you were not armed prior to the incident and appear to have shown immediate remorse."

Wilson was sentenced to five years in prison followed by two years supervision in the community following his release.
