However, more are likely to follow as the police have yet to analyse CCTV footage.
Six people were taken to hospital by ambulance to be treated for injuries as a result of football related scuffles.
Chief Minister Frank Walker has urged the courts to ‘throw the book’ at these ‘louts’.
The pictures of the violence were broadcast around the world by television news channels and Senator Walker said that the ‘very small minority of yobs had caused damage to Jersey’s reputation’.
