Summary Head of English football is concerned about the recurrence of racism and crowd trouble.
LONDON: Police said on Monday that they were working to track down the person responsible for throwing a coin at Manchester United s Rio Ferdinand during Sunday s Manchester derby.
Ferdinand was left with blood streaming down his face from a cut above his eye after being struck by a coin as he celebrated Robin van Persie s injury-time winner in United s 3-2 victory at Manchester City.
Greater Manchester Police said that they had made 13 arrests and charged nine people over offences that occurred before, during and after the match.
"To have just 13 arrests for a crowd of this size and a match of this proportion is a testament to the policing operation we put in place," said Chief Inspector Steve Howard.
"Despite fierce rivalry and high tension, there was no major disorder. However, we will continue to investigate the coin-throwing incident and are determined to work with the club to bring the perpetrator to justice."
Among the people charged were two men accused of entering the field of play during the game.
City goalkeeper Joe Hart had to restrain one young fan from getting at Ferdinand after the coin-throwing incident, prompting the United defender to thank his one-time England colleague on Twitter.
A 30-year-old man was also charged with a "racially aggravated public order" offence.
Meanwhile, the head of English football is concerned about the recurrence of racism and crowd trouble after Sunday s Manchester derby was marred by United defender Rio Ferdinand being hit by a coin and a fan arrested for racist abuse.
Football Association chairman David Bernstein says "it is deplorable to see those incidents and to see Rio Ferdinand with blood on his face is absolutely terrible."
Coins had been aimed at the United players previously during the game at City, and one hit Ferdinand after Robin van Persie s stoppage-time goal clinched a 3-2 win for United.
A City fan also ran onto the pitch toward Ferdinand but was stopped by City goalkeeper Joe Hart, while a fan was arrested for alleged racial abuse and charged Monday.
Bernstein told Sky Sports television "it s disturbing that we re seeing a recurrence of these types of incidents."
