Manchester United hosted their city rivals in an Under-21 derby on Tuesday evening but the game was marred by fan violence.
Manchester United defeated Manchester City 4-0 in an Under-21 match on Tuesday evening at Old Trafford to leave themselves within touching distance of the title.
A crowd of over 16,000 people turned up to see the spectacle but as more and more United fans came into the stadium, they gradually moved closer to the City end, eventually boxing in the rival fans into the corner of the ground.
It appears the stewards or the police did not expect such a large crowd for an U21 fixture, which both sides took extremely seriously.
Manchester City fan Andy Savage told the BBC about his horrific experience inside the City end of the ground. He said: “After half an hour, United fans were streaming in and the stewards were putting them closer and closer to our left, where we were being boxed in.
“Fights broke out and basically it was a free-for-all. There were kids screaming in the City end."
He added that fans “were being kicked and trampled on and it was very, very ugly scenes.”
Greater Manchester Police have since confirmed that they responded to a call from a fan at Old Trafford and turned up just before 9pm.
They have made three arrests, one for a youth who ran on the pitch and two more for assault but they will continue to monitor the CCTV footage of the incident.
Manchester United have refused to specifically comment on the arrests but stated that they are “aware of crowd disturbances at Old Trafford last night involving both sets of supporters.”
United need just one point from their remaining fixture to claim the U21 title and perhaps quite worryingly, face City in a rearranged return game.
