A robber set upon a man who came to complain there was too much noise outside his house.
Sean Allen, 39, has been jailed for 15 months after pleading guilty to the robbery in Fir Trees Avenue, Ribbleton.
Preston Crown Court heard the man came out of his flat asking a group of people who were gathered outside if they could be quiet on the evening of May 25 last year.
It was thought they had arrived uninvited to a party which was being held in a neighbouring flat.
The group moved to the front of the flats and the victim went to speak to another neighbour, to see if he had any control over the group.
But as the pair were talking the man was approached by two or three members of the nuisance group.
The group surrounded him and a few were “manhandling” him. Allen then went to hug the man and asked if he had a cigarette.
The man handed over a cigarette and Allen walked away, but returned seconds later to snatch the man’s wallet from his back pocket.
The wallet was later recovered but £80 cash was missing.
Allen, of Alder Road, Ribbleton, was picked out in identity proceedings and later pleaded guilty to robbery on the day he was due to stand trial.
The court heard Allen delayed entering his guilty plea as he wanted to spend Christmas with his young family.
Recorder Mark Ford, sentencing, said: “This is a serious case which calls for immediate custody. It would have been an extremely distressing experience for the victim. You maintained you were innocent of this charge and you deliberately maintained that plea of not guilty to keep your bail over Christmas.”
