Police are investigating crowd trouble which occurred at the Essex derby between Southend and Colchester on Saturday.
Footage filmed by a supporter at the game, shows a fan running towards the stand occupied by Colchester United fans.
It appears to show him throwing punches at people in the crowd. The incident took place towards the end of the League One match at Southend's Roots Hall. Police are keen to identify those responsible.
The derby was a dramatic affair on and off the pitch.
The U's will have to cope without midfielder Alex Gilbey for their next three games after he was shown a straight red card for that challenge on Ryan Leonard.
Southend scored three goals in the last ten minutes to secure a three-nil victory over their local rivals.
The father of a a teenage soldier found dead at an army barracks has told an inquest there had been an "assumption of suicide" by the police.
Private Cheryl James, 18, was discovered with a fatal bullet wound at Deepcut Barracks in Surrey in November 1995.
John Beggs QC, representing Surrey Police, said at the time the force was also investigating the murder of schoolgirl Milly Dowler and the M25 rapist.
Mr James told the court he had voiced concerns that Surrey Police's resources were "stretched" but he was told they were not.
Mr Beggs said three people had come forward to say Pte James had spoken to them about shooting herself, including one who claimed she had said: "The only way to get out of the army is to put a gun to your head."
Mr James said the comments could possibly be explained by "bravado".
Lawyers for Pte James's family had called for the inquest to be delayed to allow "important" forensic evidence to be heard before other witnesses were called.
The inquest, which is expected to last seven weeks, was adjourned until Tuesday.
A coroner has ruled that a fresh inquest into the death of a teenage soldier Deepcut army barracks should go ahead as planned, despite her family's call for it to be delayed to allow new scientific evidence to be properly considered.
A lawyer for Private Cheryl James' family, who was discovered with a fatal gunshot wound in 1995, had said the "important" pathological evidence shows it may not have been self-inflicted.
However, Brian Barker QC said there was no "practical unfairness" in scientific experts being heard later in the proceedings.
The inquest will examine new evidence suggesting Pte James, may have been sexually exploited by senior ranks shortly before her death.
High Court judges ordered the new inquest in 2014 after they quashed an open verdict recorded in December 1995.
