Family demands cross-border probe into killings of RUC officers

Police on both sides of the Irish border must launch fresh investigations into the murder of two top RUC officers following intelligence reports of Garda collusion in the killings, the family of one of the men has said.

The Smithwick Inquiry was presented with the new evidence by the Police Service of Northern Ireland (PSNI) on Wednesday as the probe into the IRA killing of Chief Superintendent Harry Breen and Superintendent Bob Buchanan in 1989 draws to a close.
