The sisters and fiancée of the murdered Belfast man, Robert McCartney, have arrived in Brussels where they have taken their campaign for justice.
While in Brussels, they are to meet with the President of the European Parliament, Josep Borrell, and MEPs.
Meanwhile, police in Belfast have released a man without charge after questioning him about the murder.
The 31-year-old, who is understood to be from the Markets area of the city, had walked into a police station with a solicitor yesterday to be interviewed.
Mr McCartney, a 33-year-old father-of-two, was stabbed to death outside a bar near the city centre on 30 January.
The IRA later admitted that three of its members were involved in the attack.
Since his killing, Mr McCartney's family has carried out a high profile campaign aimed at bringing his attackers to justice.
The campaign included a visit to US President George W Bush at the White House.
