PSNI chief constable Hugh Orde has said he is still hopeful of bringing prosecutions in relation to the murder of Belfast man Robert McCartney.
The 33-year-old father-of-two was beaten and stabbed to death outside a pub in the city on January 30, allegedly by senior IRA members.
Speaking at the launch of crime figures in Belfast today, Mr Orde said: "There's always hope . . . We will do our best to bring those [responsible] to justice . . . We're working on that."
