© Provided by The Independent A man has been arrested after a police officer suffered serious facial injuries during last week's protest by Manchester United fans against the club's owners, Greater Manchester Police (GMP) said.
The 25-year-old was arrested on suspicion of grievous bodily harm with intent, violent disorder and burglary, police said.
Officers took the man into custody after bringing a warrant to an address on the Wirral in Merseyside on Tuesday.
A police statement said: "The arrest was in relation to a breach of the Manchester United grounds and an officer who was left with a broken eye socket, broken nose and a slash to the face after an object was thrown at his face. He continues to receive medical treatment for his injuries."
GMP said a number of officers were injured in the protest which saw about 1,000 fans gather at Old Trafford and about 200 at the Lowry Hotel in Manchester ahead of the team's match against Liverpool on Sunday 2 May.
