A man has been arrested over an alleged assault against Roy Keane during Arsenal vs Manchester United on Sunday.

An investigation is underway after a member of the public allegedly aimed a headbutt at the former United midfielder during the Premier League game at the Emirates Stadium.

A 42-year-old man has now been arrested and taken into custody while enquiries continue.

A statement from the Metropolitan Police on Monday read: “On Monday, 4 September, a 42-year-old man was arrested on suspicion of assault (ABH). The man has been taken into police custody.”

The incident occurred during the latter stages of the match, shortly after Alejandro Garnacho thought he had given United a late lead.

Keane and fellow Sky Sports pundit Micah Richards were travelling between the studio and the pitch when the altercation occurred with a member of the public, who allegedly aimed a headbutt at Keane and caught him on the chin and chest.

A witness to the situation said Keane was startled but did not react aggressively while Richards asked the man to apologise.

The confrontation spilled over into a hospitality area where Richards attempted to defuse the situation before it is understood the man in question fled the scene and left the stadium.

Video footage of the incident appeared on social media on Sunday evening.

A Sky Sports spokesperson said: “We understand the police are investigating an alleged assault by a member of the public immediately preceding the footage circulating on social media. In the footage seen, Micah Richards was acting to defuse a situation.”

Arsenal are cooperating with authorities.

A club spokesperson said: “We are aware of an incident that took place during our match against Manchester United on Sunday.

“The Metropolitan Police is conducting an investigation into the matter and we are fully cooperating with their enquiries.”

Arsenal went on to win the game after Garnacho’s strike was disallowed for offside with goals from Declan Rice and Gabriel Jesus in stoppage time confirming a 3-1 victory.

They return to action following the international break against Everton.
