Manchester United and Liverpool are both facing disciplinary action from Uefa following their heated Europa League last 16 second leg tie at Old Trafford. Five people were arrested as fans clashed inside the stadium towards the end of the match which finished 1-1, sending Liverpool through to the quarter-finals 3-1 on aggregate.
Two Liverpool fans were arrested on suspicion of affray following physical confrontation and a third was given a police caution for letting off a flare in the stands during the match. There were also unconfirmed reports of seats being ripped up and objects thrown during the scuffles.
Uefa have now confirmed that both teams will be investigated and face possible disciplinary action over the incidents at Old Trafford. Manchester United face charges of blocking stairways, crowd disturbances and throwing of objects.
Liverpool have been charged with illicit chants, setting off of fireworks, throwing of objects, crowd disturbances and late kick-off. The case will be dealt with by the Uefa Control, Ethics and Disciplinary Body on 19 May.
Greater Manchester Police confirmed the arrests but praised the majority of the fans who attended the game. Superintendent Jim Liggett said: "The policing operation for the Manchester United v Liverpool match has now come to an end and towards the end of the game there were a handful of concerning incidents which are currently being investigated. We have made a total of five arrests.
"However, the behaviour of the majority of fans in attendance was excellent and I would like to thank them for their co-operation throughout."
Prior to the game, a picture emerged on social media of a banner reading "murderers" along with the date of the Hillsborough Disaster draped over a bridge on the M602 motorway near Manchester which joins the two cities. Police said they were made aware of offensive banner and officers were "immediately dispatched" to take it down.
