A 23-year-old Sheffield United fan has been bailed after being arrested following trouble after Saturday’s match at Port Vale.
Staffordshire Police initially reported that two officers had been hurt following clashes between fans, with one suffering cuts to his face after being struck with concrete and a second taken to hospital with a suspected fractured ankle.
But the force has now confirmed the second injury to an officer, a female Special Constable, was not related to disorder at the ground and she is recovering from a sprained ankle.
A spokeswoman for the force said a 23-year-old man from Sheffield, who was arrested on suspicion of affray following the disorder, has now been bailed while enquiries continue.
Police will be reviewing police video and club CCTV footage following the disorder at Vale Park in Stoke-on-Trent.
Disorder occurred as small numbers of supporters from both clubs attempt to clash with each other near to the coach park.
Superintendant Wayne Jones from Staffordshire Police said: “There were no reported incidents of disorder in the run up to the match with both sets of fans behaving well.
“During the game the stewards ejected two people from Port Vale sections of the ground without the need for policing support.
“The incidents post-match were quickly dealt with by the police and stewards working together and the male arrested for affray and assault from the Sheffield area has been released on police bail pending further enquiries taking place.”
