Local cops blast Man City striker Adebayor
A police spokesman told the Daily Mail: "A player in a goal celebration caused the opposition fans to be aggravated. There was a crowd surge. An object has been thrown and caught a steward and knocked him out. We have not arrested anyone for that.
"It's down to the club, ground security and the FA whether they want to take the incident any further. It must have been horrific for the stewards at the time.
