Nine bailed over Stoke-Cardiff FA Cup game disorder
Nine people arrested following disorder before and after an FA Cup match have been released on police bail.
The arrests for public order and criminal damage offences related to Stoke City's 1-1 draw with Cardiff City at the Britannia Stadium on Saturday.
The arrested males, aged between 13 and 34, were released on police bail until February while investigations continue.
A number of police officers were attacked and one was taken to hospital with a leg injury, the force said.
The officer was treated for muscular damage and was expected to make a full recovery.
Two 15 year-olds, three 16-year-old youths and a man aged 27, all from the South Wales area, were among those bailed.
A 26-year-old man, a 13-year-old boy, both from Newcastle-under-Lyme, and a 34-year-old man from Stoke-on-Trent were also bailed.
Staffordshire Police said officers were examining CCTV film as part of their investigation into disorder following the match.
Supt Pete Owen said: "At the end of match on Saturday officers took positions to prevent the two sets of supporters from clashing.
"It was clear that a minority of younger fans were intent on becoming involved in disorder with supporters from the opposing team.
"Those officers became the target of the disorderly behaviour as significant number of local young people, who continually refused to disperse from the area around the stadium, attacked the officers."
