Roy Keane was allegedly 'giving it to the Arsenal fans' when Manchester United scored in their thrilling Premier League clash last weekend.
Keane and fellow Sky Sports pundit Micah Richards were involved in a furious altercation with a supporter during Arsenal vs. Man United.
A shocking video shows the ex-Manchester City defender detaining a person, who reportedly headbutted the former Man United captain, which resulted in the fan's arrest.
The Metropolitan Police have since confirmed a 42-year-old man has been arrested.

It is claimed that Keane and Richards were walking from the Sky Sports studio towards the pitch in order to conduct their post-match analysis.
While the Irishman waited for a lift to take him down to the pitchside area, a man aimed a headbutt, hitting him on the chest and chin.
Fresh reports, however, now claim Keane was 'giving it to the Arsenal fans' following Marcus Rashford's opener, which would up the Emirates faithful.
A source told The Sun: "Keane was giving it to the Arsenal fans when United scored, and it wound some up. He seemed to be provoking them.
"He broke his nose and Keane didn’t seem to be hurt at all, just a bit shaken up."
Another supporter who witnessed the incident added: "The fan seemingly tried to headbutt Roy Keane.
"Micah Richards stepped in and pushed the fan back against the door. I heard the altercation and I was shocked to see the individuals involved."
In a statement, Sky Sports 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."
Keane and Richards were left 'shaken' by the incident but continued their Sky Sports duties.
As a result of the clash between Keane and the fan, the company will review their security for its pundits for the rest of the season.
