A gym worker failed to do unpaid work for the community after launching an unprovoked attack on a man, a court has been told.
Scott Sykes only did one-and-a-half hours payback work out of the 150 hours he was ordered to complete by a court.
Sykes, 28, of Stockydale Road, Marton, was found guilty of breaching a court order after a trial in his absence.
He was sentenced to 12 weeks in prison suspended for 12 months and put on a three months curfew from 10pm to 8am by Blackpool magistrates.
Neal Brookes, prosecuting for the probation service, said a man had accidently bumped into Sykes coming out of a nightclub.
The man apologised, but Sykes punched him in the face and knocked him to the ground, chipping some of his teeth.
For this assault he had been sentenced to 150 hours unpaid work.
Another 50 hours were added when he breached the order on the first occasion. He had done only one-and-a-half days of the work.
David Charnley, defending, said Sykes had had a terrible year with his partner suffering post-natal problems.
His partner had now taken the children and left him, the court was told.
