A ST ANNES man left a party and launched an unprovoked attack on a passer-by, a court heard.
Peter Gillett, 20, punched his victim several times.
Gillett of Walter Avenue, admitted assault and breaching the terms of his Anti Social Behaviour Order when he appeared before Blackpool magistrates.
Pam Smith, prosecuting, said the victim was walking through St Annes after an evening out when he was hit from behind on the head.
He did not see his attacker before he fell to the ground.
However, the assault was witnessed by people who had been at the party and saw the victim repeatedly punched by Gillett.
They pulled him off the man and called police.
When interviewed by officers Gillett initially denied being involved.
The prosecutor told magistrates Gillett was awaiting sentence for theft allegations and another breach of his Asbo.
The case against him was adjourned for pre-sentence reports.
