A teenage thug who had an anti-social behaviour order slapped on him has been jailed.

Daniel Sallis was given 18 months in a young offenders institute for assaulting another youth, shop burglaries and driving offences.

Sallis, 19, also breached his Asbo by being a passenger on a motorbike, Hove Crown Court heard.

Worthing magistrates imposed the ban in 2002 preventing him from swearing in public or using threatening or abusive behaviour.

Sallis, of Summersdeane, Southwick, was also banned from driving or allowing himself to be carried on a motorbike or moped unless he had a licence.

Walton Hornsby, prosecuting, said he breached the Asbo when he was seen as a passenger on a motorbike in October last year.

Four days later Sallis walked into the back of a mobile phone shop in Brighton and stole four phones worth £596.

Sallis also stole tins of chocolate worth £200 from the back yard at Sainsbury's store in Rustington two weeks before Christmas.

He was one of three men who forced open the door of the deputy head's office at Oathall College, Haywards Heath, while adult education classes were taking place in February.

Sallis was identified after footage from CCTV cameras at the college were examined.

Mr Hornsby said: "The following day he was in the Mill House pub in Hove and there was an altercation between him and a group with Gary Meaker.

"Sallis went into the gents and punched Mr Meaker three times in the face."

Sallis, who does not have a licence and is disqualified from driving, was also seen driving a van in Southwick in May.

He has spent time in young offenders institutes for earlier offences and has been on remand awaiting sentence for four months.

Adrian Fleming, defending, said Sallis realised that he had an unenviable criminal record for someone of his age.

Mr Fleming said Sallis found he could cope with life in a young offenders institute and was in danger of becoming institutionalised.

He added that Sallis had the support of his parents and family and wanted to take advantage of a place on a persistent young offenders programme when he is released.
