Manchester United have vowed to ban any fans found to have been involved in criminal or violent behaviour during Sunday's anti-Glazer protests at Old Trafford as police confirmed they had arrested a 28-year-old man after clashes with officers.

A number of supporters forced their way into the stadium, leading to the postponement of their Premier League match at home to Liverpool, as a demonstration against club owners the Glazer family escalated into incidents of violence and damage.

Greater Manchester Police said six officers were injured after the protests turned "hostile" when demonstrators threw flares, bottles and barriers at police.

The postponement has given Premier League planners a headache as United are scheduled to play every midweek until the end of the season, meaning the most likely option is to stage the match on the weekend of the FA Cup final (May 15/16), with Liverpool's game against West Brom brought forward to accommodate that.

"Information on the rescheduling of the game and any possible implication on other fixtures will be announced after discussion and agreement with the Premier League," said United.

The Football Association, which is investigating the incidents at Old Trafford, took a dim view of fans' behaviour.

"We understand their frustrations. However, we cannot condone the violent and criminal behaviour that took place before the scheduled Manchester United v Liverpool match, which the FA is now investigating," said a statement.
