The Metropolitan Police have launched an investigation into an alleged assault involving Roy Keane during Manchester United’s defeat to Arsenal at the Emirates. Keane, who was working for Sky Sports on the day, was allegedly headbutted by a fan after an altercation during the game on Sunday afternoon. A clip has since emerged on social media, in which Roy Keane and fellow Sky Sports pundit Micah Richards can be seen confronting a man. It is unconfirmed at what point during the game the incident took place. The clip does not appear to show the alleged incident taking place but it does show Richards holding the shirt of a man and confronting the individual. Keane appears in the background of the short clip talking with the man and Richards. The pair were working the game alongside former Arsenal forward Theo Walcott In a statement, the Met Police said: “Police are investigating following an assault that is alleged to have occurred at the Emirates Stadium during an Arsenal v Manchester United match on Sunday, 3 September. “There have been no arrests. Enquiries are ongoing.” Sky Sports have confirmed on their website that the former United captain and City right-back have given statements to the police. In a statement, a spokesperson for the company 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 diffuse a situation.” On the pitch, it was Declan Rice and Gabriel Jesus’s injury-time goals that secured a dramatic 3-1 victory for Mikel Arteta’s side against United. Arsenal conceded the game’s opening goal courtesy of Marcus Rashford’s curling effort but hit back less than two minutes later when Martin Odegaard swept home from the edge of the box. In the second half, Kai Havertz thought he had won a penalty after a challenge from Aaron Wan-Bissaka, only for the decision to be overturned after a VAR check. Erik ten Hag’s side then thought they had won the game late on when Alejandro Garnacho slotted home in the 87 minute. In a second contentious VAR decision, the Argentine’s goal was ruled out for offside before Rice secured the win for Arsenal with a deflected effort from a corner and his first goal for the club. Deep into injury time, the returning Jesus would add a third with a composed finish on the break.
