A man who left the daughter of former Middlesbrough football manager Bryan Robson scarred for life was today jailed for three months.

Mark Bregazzi, 20, must also pay £1,000 compensation to Claire Louise Robson for injuries inflicted with a head butt in a late night confrontation outside a Durham taxi office.

Durham magistrates heard that Bregazzi carried out the assault after making a disparaging remark about her father, the former England and Manchester United captain, over his time in charge at Middlesbrough.

Miss Robson pushed him away and he responded by delivering the blow which resulted in her being detained overnight in hospital, where she was given ten stitches to a 4cm laceration across her forehead.

Bregazzi, an apprentice plasterer, of Dominion Road, Brandon, near Durham, admitted causing her grievous bodily harm at an earlier hearing.

He returned for sentence today, when the court was told Miss Robson has undergone examination by a plastic surgeon since the attack.

The consultant's report, read to the court, said despite receiving treatment, the scar "will unfortunately remain with her for the rest of her life".

In a victim statement, also read to the court, Miss Robson described the attack as a "traumatic experience", the full effect of which only really hit her days after the incident.

She said she has suffered psychologically and is now reluctant to go out in public in case anyone recognises her.

"I'm always aware of people around me when doors open," she added.

John Grierson, for Bregazzi, said his judgement was affected by the amount he had drunk that night, but claimed he used his head merely to push away Miss Robson.

He said due to the fame of his victim and the publicity the case has generated he has received threats from "supporters of the other team".

Mr Grierson added that Bragazzi, with no previous convictions, would now lose his job. Jailing him, magistrates' chairman Kevin Storey said the bench "totally disregarded the high profile nature" of the victim in reaching their decision.

A further hearing will be staged on Bregazzi's release to decide how he can meet the compensation award.

Miss Robson, from Chester-le-Street, declined to comment after the hearing.
