A vulnerable pensioner was left permanently disfigured after being hit in the face with a cup as he was robbed in his own Leeds home.
The 70-year-old victim was attacked at his flat in the Burmantofts area of Leeds after he allowed Ashley Keenan into his home.
A court heard how the victim had befriended Keenan only to be violently assaulted after Keenan stole his wallet.
Keenan, 20, who has a history of committing burglaries and violent offences, then threatened to hit the victim again unless he handed over the rings from his fingers.
Keenan, of Wellhouse Place, Little London, Leeds, was given an extended prison totalling ten years for the attack which took place in August last year.
Leeds Crown Court heard the victim challenged Keenan soon after allowing him into his when he realised his wallet was missing.,
Keenan was drinking from a mug at the time and used it to strike the victim in the face. He then told the 70-year-old he had a knife and would stab.
The pensioner was then told he would be hit in the face with mug again unless he took off his rings.
Keenan left the property after the attack but was arrested when police were contacted and his DNA was found at the scene.
The court heard the victim needed stitches to a wound to his forehead and lower lip and has been scarred for the rest of his life.
Keenan initially denied responsibility for the attack and refused to comment during interview. He later pleaded guilty to robbery, unlawful wounding and theft.
Keenan also pleaded guilty to a burglary committed at a shelter for homeless people in Wortley on August 15.
Graham Parkin, mitigating, described Keenan as an isolated individual. He said his client had a personality disorder which was made worse by alcohol abuse.
Mr Parkin said: “In his own terms, he’s been an idiot and he accepts that the complainant would have been caused severe anxiety.”
Judge Rodney Jameson, QC, told Keenan he must go to a young offenders institution for seven years and serve an extended three-year period on licence.
He said: “I have no doubt that as things stand you are not only a significant, but a substantial risk of causing serious harm to others.”
