A festive reveller who smashed a bottle in a man’s face as he spent Boxing Day at home with his elderly mother has been jailed for three-and-a-half years.

Drunken Richard Singh lashed out with a Sambuca bottle, embedding glass in Neil Savage’s face and damaging the sight, Bradford Crown Court heard on Tuesday. Singh, 26, of Queen’s Road, Ingrow, pleaded guilty to unlawfully wounding Mr Savage, a 52-year-old diabetic.

Prosecutor Richard Smith said Singh visited Mr Savage’s home, in Bracken Bank Grove, Keighley, at 8.30am on December 26 last year. He was clutching the Sambuca bottle.

Singh said he was a friend of Mr Savage’s son and he was invited into the house, where Mr Savage lived with his mother, who is in her 70s.

Singh became agitated, swinging the bottle and threatening to hit Mr Savage with it. As Mr Savage wrote down his son’s contact details, he felt a blow to the head and began bleeding from a wound, the court was told.

Singh ran from the house, leaving behind the broken bottle.

Mr Savage was treated in Airedale Hospital where smashed glass was extracted. His eye was bleeding and doctors feared a detached retina and transferred him to Bradford Royal Infirmary for an eyesight check.

Mr Smith said Mr Savage, who had cataracts in his right eye, suffered impaired vision in his left eye from the attack.

He needed operations and was suffering from stress.

Singh, who was arrested three days later, had convictions for punching a man in 2005, three offences of battery in 2010 and taking part in a large-scale affray in Keighley town centre.

Singh’s solicitor advocate, Julian White, said his client had serious mental health problems, including paranoia, brought on in some part by alcohol and substance abuse.

He had not known what he was doing when he was at Mr Savage’s home.

Now drug and alcohol free, Singh was a trained plasterer and the father of two children.

Judge Peter Benson jailed Singh for three years for unlawful wounding and an extra six months for breach of a previous court order.
