The sisters of murdered Belfast man Robert McCartney have vowed to take their campaign to bring his killers to justice to Britain and America.
They claim the men who murdered their brother are still walking the streets of Belfast.
As the McCartney family maintains its pressure, a 29-year-old man has handed himself over to police.
He is not one of the three IRA members expelled from the organisation on suspicion of being involved in Mr McCartney's murder. The father-of-two was stabbed to death outside a Belfast pub on 30 January.
In another development, the Minister for Foreign Affairs, Dermot Ahern, has told the Dáil that only information given directly to the PSNI will put the killers of Mr McCartney behind bars.
He was speaking during a debate on a Fine Gael motion calling on those with knowledge of the crime to give statements to the police. The debate concludes tomorrow evening.
The motion is being backed by the Government, and most of the other Opposition parties, with such overwhelming support it will not have to be put to a vote.
It calls on public representatives to actively encourage witnesses to Mr McCartney's murder to give statements to the police.
Sinn Féin says it supports the thrust of the motion, but wants it amended to say that witnesses who do not trust the PSNI should be able to give information to a solicitor instead.
Fine Gael leader Enda Kenny dismissed this suggestion as a cop-out, while Minister Ahern said that until the killers are brought before the courts, no member of the Provisional movement can utter the words truth or justice with any credibility.
Orde comments on case
Earlier the PSNI's Chief Constable, Hugh Orde, said some people wanted for questioning about the murder have left Northern Ireland.
In response to enquiries concerning these comments, a PSNI spokeswoman said this afternoon this was no longer the case. She said the PSNI would be making no further comment as the investigation is live.
Meanwhile, the Northern Secretary, Paul Murphy, said the IRA's decision to expel three of its members because of their suspected involvement in the killing did not go far enough.
