Police confirm 11 arrests at Carling Cup derby
Manchester United are expected to impose indefinite bans upon any fan found guilty of throwing missiles during Wednesday's Carling Cup semi-final second leg.
Greater Manchester Police have confirmed that 11 men have been arrested on suspicion of various offences in build-up to United's 3-1 win over Manchester City at Old Trafford.
It is believed that the fan who threw a bottle of cider at City's Craig Bellamy as the Welshman was about to take a corner during the second half has since also been detained.
CCTV footage will now be studied in an effort to identify another hooligan who threw a coin that struck Bellamy on the back of the head at around the same time.
It is expected that Police will then request immediate bans from United for any guilty parties, while the Football Association may also impose fines upon the club.
"Once we have the referee's report and asked for a report from the club itself we can establish what, if any, action is merited," said an FA spokesman.
Excellent work
A Police spokesman said on Thursday: "Officers policing (last night's) Manchester derby have made 11 arrests.
"Eleven men have been arrested on suspicion of various offences, including public order, affray and criminal damage."
Assistant Chief Constable Ian Hopkins said: "The arrests we made prior to (last night's) game and the work we carried out with the clubs has paid dividends.
"The vast majority of fans have taken on board our messages ahead of the game, making sure it has been a safe evening and one that can be remembered for the football.
"The low number of arrests on the night is testament to the excellent work of all those involved.
"The vast majority of fans behaved very well and I would like to thank them for listening to the messages we have been giving, to help make the evening pass off peacefully."
