Manchester United will punish fans who committed criminal acts during the protests on Sunday which led to the Premier League game against Liverpool being postponed, the club said on Monday.

United fans protesting against the club's American owners, the Glazer family, stormed into the stadium which was closed to fans due to Covid-19 restrictions.

Trouble caused by protests from fans has been criticised by British Prime Minister Boris Johnson, but he said that he understood the "strength of feeling".

"The club has no desire to see peaceful protestors punished, but will work with the police to identify those involved in criminal activity, and will also issue its own sanctions to any season ticket holder or member identified, per the published sanctions policy," United said in a statement.
