**Manchester City striker Craig Bellamy is being investigated by police after an altercation with a supporter during the 4-3 derby defeat at Old Trafford.**Greater Manchester Police said inquiries were under way but no-one had made a formal complaint.
City manager Mark Hughes defended the Welshman’s actions.
Fans are forbidden to enter the field of play and Hughes said: “I did not see it but the guy should not have been on the pitch. That is not acceptable.”
He added: “Brian Clough clipped someone’s ear. He was lauded a national hero. Maybe it’ll be the same with Craig but I doubt it.”
The Manchester United fan came onto the pitch after Michael Owen’s late goal which sealed the hosts’ dramatic victory over rivals City.
In a hotly-contested derby battle, the Blues came from behind on three occasions with Bellamy scoring two magnificent goals, including an equaliser to make it 3-3 in the 90th minute.
Hughes also confirmed substitute Javier Garrido was struck by a coin thrown from the home section of the stadium at half-time.
It is likely that former United hero Carlos Tevez had been the target, as he was stood near Garrido when the coin was thrown.
The Argentine, who moved across to Eastlands in the summer, was booed throughout the match by some of the home supporters.
Garrido was not hurt, but the Football Association could be called upon to pass judgement on the two incidents.
“Something came from the crowd but he is OK,” Hughes added.
City striker Emmanuel Adebayor is already facing an FA improper conduct charge after running the length of the pitch to celebrate in front of Arsenal supporters after scoring against his former team.
