Detectives have released CCTV images of a man they want to speak to following a pitch invasion at the Preston Blackpool cup match last month.
The game was marred by crowd trouble and damage to parts of Deepdale stadium.
This man is wanted in connection with offence against the steward.
At the final whistle a number of supporters ran onto the pitch in celebration at the result.
This incursion onto the field of play is totally unacceptable and is condemned by everyone connected with Preston North End Football Club.
Contrary to early press reports the steward that was seen on TV in contact with a police horse was not taken to hospital and went home with colleagues after being given the all clear by medical staff at the ground.
The only steward to receive any injuries at the stadium was working in a part of the stadium occupied by the visiting supporters.
The behaviour of those involved in the disorder at last night’s game was completely unacceptable – there was a significant minority of determined people from both sides who throughout the day, before, during and after the game, were intent on causing problems.
There will be a thorough investigation over the coming days and weeks and I want to be very clear that those involved in the disorder can expect a visit from the police and to be prosecuted.
The behaviour of those involved in the disorder and the behaviour of some people towards officers and stewards was absolutely disgraceful.
This was a very difficult situation which presented significant challenges for both the club and for ourselves and we were able to bring the situation under control quickly.
The disorder last night was completely unacceptable and we will be making significant efforts to locate and prosecute those involved.
