Assembly members from all political parties have appealed for anyone with information on the sectarian attack on Derry civil servant Paul McCauley to come forward to the PSNI.
Mr McCauley was left in a permanent vegetative state after being attacked by a group of up to 15 people at a barbecue in the Spencer Road area of the city in July 2006.
To date only one person has been convicted in connection with the attack.
The call for information was made at an adjournment debate at Stormont on Monday evening, secured by Foyle MLA Martina Anderson.
Five of the six Foyle MLAs took part in the debate and supported the call for fresh information. Assembly protocol meant that DUP MLA William Hay could not take part in the debate because of his role as speaker but he also supported the call outside the chamber.
Ulster Unionist MLAs Basil McCrea, Roy Beggs, and deputy party leader, John McCallister, and DUP MLA and Policing Board member Jimmy Spratt also spoke during the debate and called on anyone in the unionist community who may be shielding Mr McCauley’s attackers to come forward.
Justice Minister David Ford also spoke and said the PSNI have assured him they are doing everything they can to bring the gang to justice.
