A have-a-go amusement arcade owner was left injured after he chased and tried to collar a would-be burglar.
Jordan Hart was involved in a struggle with defendant Benjamin Robinson, 27, after he noticed the thief stealing £363 from one of his machines.
Preston Crown Court heard Robinson, 27, of Bradford, West Yorkshire, was spotted acting suspiciously near a machine, with a female accomplice trying to shield him from view.
He forced his way out of the premises after Mr Hart and his brother Charles confronted him, but was later caught by police on the M55 after his registration number was noted down.
Robinson, who had 23 previous convictions, was given 46 weeks jail by Recorder Tanya Griffiths QC.
His girlfriend at the time, Kerry Lannen, 24, also of Bradford was given a two years conditional discharge.
She had also admitted theft.
The offence was carried out in February this year.
Louise Santamera, prosecuting, said the Hart brothers were on duty at the arcade in North Shore at the time.
One of them saw Robinson put a metal implement in a machine and take money.
He told his brother Jordan, who immediately called the police.
The defendants tried to leave while the police were being called.
Miss Santamera told the court “The brothers confronted them.
“A minor altercation took place, during which Jordan Hart suffered some bruising.
“Benjamin Robinson was acting in an aggressive and abusive way, forcing his way out before escaping in a car.
“Jordan Hart went after him, chasing the car and managed to obtain the registration number.”
Police who caught Robinson found £200 in bank notes in his car, and reported metal objects and pound coins being thrown from the vehicle.
Mr Hart still does not have full use of his thumb after sustaining an injury during the chase.
He went to Blackpool Victoria and ended up wearing a splint for five weeks and having physiotherapy on his left thumb.
Leila Ghahhary, defending Robinson, said he deeply regretted his actions that day.
“At the time of the offence he was out of work, in financial need and had what I would describe as quite a serious gambling addiction.”
Wayne Jackson, for Lannen, who had no previous convictions, said the relationship with Robinson had now ended.
