CCTV pictures from the Preston North End v Blackpool disorder in August have been released.
Police are wanting to speak to a man and a woman following incidents of disorder before, during and after the Capital One Cup game at Deepdale.
Lancashire Police say they have arrested 15 people who are currently on bail and six have been charged with a number of offences relating to the disorder.
Fans ran onto the pitch following Preston’s 1-0 victory over arch-rivals Blackpool, sparking a major police investigation.
Detective Inspector Paddy O’Neill from Preston Police who is leading the investigation said: “Over the past couple of months we have been studying CCTV footage from various sources, and interviewing witnesses and suspects. We need the public’s help to identify this pair as this will conclude this particular phase of the investigation.”
“If anybody recognises either of these people I would ask them to contact police.”
Anyone with any information should call police on 101 or contact the independent charity Crimestoppers anonymously on 0800 555 111 or on-line at Crimestoppers-uk.org.
