A man stabbed his neighbour on Boxing Day, leaving him with life-changing injuries, a court heard.
His victim was taken to hospital where he underwent surgery for damage to tendons in his hand.
He has been left with permanent damage which restricts his movement.
Aitzaz Sadiq, 36, was described by the victim as appearing drunk when he threatened him in Bamber Street, Peterborough, at about 10pm on 26 December.
The victim, a man in his 20s, walked away to Cromwell Road but Sadiq followed and attacked him from behind.
Sadiq punched him to the back of the head, causing the victim to fall over, before stabbing him in the hand and causing a laceration to his neck.
The victim managed to escape and run to home. A short while later Sadiq arrived at the property in Cromwell Road, shouted in the street and smashed a front window.
Police were contacted and he was arrested.
The victim was taken to hospital where he underwent surgery for damage to tendons in his hand.
He has been left with permanent damage which restricts his movement.
Sadiq, of Cromwell Road, Peterborough, admitted wounding with intent, possession of a knife in a public place and criminal damage.
On Friday (7 July) at Peterborough Crown Court he was jailed for nine-and-a-half years.
DC Andrew Donaldson said: “This was a vicious, unprovoked attack that has left the victim with life-changing injuries.
“The damage caused to his hand restricts his movement and therefore impacts on his ability to do tasks and work.
“I’m pleased Sadiq has now appeared in court and faced justice.”
