Police are looking at CCTV footage to identify hundreds of football fans who ran riot in Derby city centre.

Violence erupted after two coachloads of Sheffield United fans stopped off in Derby after travelling back from watching a game in Coventry.

About 150 fans from the Yorkshire club attacked two pubs near The Spot before fighting broke out with Derby County fans at about 1830 BST on Saturday.

Police said they had no tip-offs about the visit and had stood down after the game between Reading and Derby had earlier passed off peacefully.

Running battles

Video tapes of the fighting have been recovered from business premises and the city's CCTV system.

Detectives from Derbyshire Police say they will spend the next few days examining the footage and expect to make further arrests.

The coaches stopped in London Road and the Sheffield fans attacked two nearby pubs causing thousands of pounds worth of damage.

Running battles then began between the Sheffield fans and Derby County supporters in St Peter's Street.

After police regained control, the Sheffield fans were searched and photographed by police before being transported out of the county.
