A convicted killer who threw sulphuric acid on a man in a supermarket has been jailed.

Thomas Charnley has been sentenced to four years and five months in prison for hurling the liquid from a jar at Scotmid in Viewpark, North Lanarkshire.

Daniel Duffy, 38, suffered blisters to his skin as the toxic liquid began to burn following the attack in April.

Charnley, 44, fled after the attack which was captured on CCTV.

At the High Court in Glasgow, he admitted assaulting Mr Duffy to his severe injury.

Jailing him, judge Lord Burns said: "This was a bad attack on a man in a public place with acid. It is fortunate he was not more seriously injured. I consider you pose a serious risk of harm to the public."

Lord Burns ordered Charnley to be monitored in the community for three years after his release from prison.

Prosecutors believe the substance used in the horrific attack was sulphuric acid or a similar liquid.

The court heard he threw the acid over Mr Duffy as they both shopped in the Scotmid Store.

Charnley, who was clutching a dark jar, threw its contents at Mr Duffy as they met in an aisle.

Mr Duffy initially managed to grapple with Charnley as shocked workers looked on. But staff had to come to his aid when the effect of the acid took hold.

Blisters appeared on his head and neck and he went into shock.

He headed home and when police arrived he was standing over a bath getting water poured on him.

The acid also burned holes into his trousers. He received hospital treatment but did not suffer permanent scarring.

Charnley was jailed for murder in 1997 after he beat a man to death in Coatbridge, North Lanarkshire.

He was initially freed from his life sentence in 2009 but was recalled to prison after getting into trouble and was released for a second time in 2015.
