British police investigating the attack on an Irish man before Liverpool’s Champions League semi-final at Anfield last month are appealing for CCTV and camera phone footage.
Father-of-three Sean Cox, 53, from Dunboyne, Co Meath, remains critically ill following the assault outside the stadium ahead of the first leg tie on Tuesday 24 April.
Detective Inspector Paul Speight, of Merseyside Police, said: "Sean Cox remains in hospital in a critical condition at Walton Neurological Centre. Our thoughts are very much with his family who are going through an extremely tough time, and we want to bring anyone responsible to justice.
"We have studied CCTV footage and have spoken to a number of witnesses, and I want to thank the people who have already come forward for their ongoing support.
"We know there were a number of people filming on camera phones before and after the incident, and we are very keen to hear from them and view the footage as it could prove vital to our investigation of this incident."
Fighting erupted near The Albert pub, close to the ground, shortly before kick-off, where it is believed Mr Cox was hit with a belt and fell to the ground at 7.08pm.
Damien O'Reilly, a councillor in Co Meath, described Mr Cox as a role model and cornerstone of the community and heavily involved in local Gaelic football.
In a statement, Mr Cox's family said he is "the most amazing and wonderful husband, dad, friend, son, uncle, and brother, and he has brought us all nothing but joy".
Earlier this week the Cox family said they were "overwhelmed and humbled" by public support since the incident.
