Police have issued CCTV images of fans they believe were involved in disorder at last week's Manchester derby. A total of 18 arrests were made following the Carling Cup semi-final first leg between Manchester City and Manchester United and more trouble is feared at Wednesday night's return leg.

"The people who caused the disorder are a disgrace to the vast majority of peaceful and genuine fans who simply wanted to enjoy the match. "When we catch these people, and be assured we will, they could become subject to football banning orders, which in simple terms means they will be banned from attending football matches.

"These people must be held accountable for their behaviour." More...
