Sheffield United fans have been warned they could face banning orders after children as young as 10 were injured after more than 200 football fans fought in a coach park.
Officers arrested five people as fighting broke out following the Middlesbrough vs. Sheffield United game in the Championship on Saturday, which left one officer in hospital.
Disorder began just before the final whistle when United fans thought their team had scored a last-minute equaliser, only for it to be disallowed.
Video footage on social media then showed scuffles taking place in the coach park after United fans managed to get through a gate towards Boro fans, as children and elderly fans looked on in fear.
