A MURDERER who stabbed a teenage boy through the heart at a disco was yesterday jailed for two years after carrying out a bottle attack at a Renfrew pub.

Scott Smith was given a life sentence in 2000 for killing fellow 16-year-old Graham Newton on the dance floor of a council-run bash for under-18s.

Smith kneed his victim in the groin and then plunged a marble-handled lock-knife into his heart.

He was ordered to serve a minimum of 10 years behind bars for the murder, which took place at the Ikon club in Old Sneddon Street, Paisley.

Smith, who was released back into society in 2013, is now 35 and married with a three-year-old child.

However, he has been locked up again after admitting a bottle attack at Davidson’s Bar, in Hairst Street, Renfrew – a pub where his wife is the joint licence holder – on March 2.

He casually poured lager out of a bottle before spinning it round so the neck was sticking out and smashing it into the face of Stuart Mack, leaving blood pouring from a wound that medics later had to sew.

Smith admitted the attack when he made a previous appearance at Paisley Sheriff Court, pleading guilty to assaulting Mr Mack by striking him on the head with a bottle to his severe injury.

When he returned to the dock yesterday to learn his fate, he was told his latest jail term would be reduced from three years as he had admitted his guilt.

Defence solicitor Rhona Lynch said Smith knew a prison sentence was inevitable but he had “shown remorse and witness empathy” and has been counselling other inmates about drugs and alcohol while on remand over the offence.

She added: “He wishes to apologise in open court to the complainer, his wife and family and to the court for his actions.”

Sheriff David Pender told Smith: “Well, you clearly have a supportive wife and a lovely little boy. That aside, due to the nature of the offence and your previous convictions, it would have been a sentence of three years.”

The sentence was backdated to when Smith was first remanded in custody.
