Officers investigating the murder of Detective Garda Adrian Donohoe have launched a fresh hunt for his killers.
Detectives from Dundalk backed up by specialist officers from the Garda divisional search team, regional support unit, national bureau of criminal investigation and scenes of crime unit have carried out planned searches at Faughart, close to the scene of the shooting in Co Louth.
Detective Garda Mr Donohoe, a 41-year-old father of two, was shot dead as he responded to a robbery at Lordship Credit Union in Bellurgan, Jenkinstown, in January.
He was hit in the head seconds after he got out of his patrol car to confront the gang.
Last month, police on both sides of the border carried out searches in Carlingford and south Armagh.
A Garda spokesman said the investigation was active and ongoing. He renewed appeals for members of the public to come forward with any information they may have relating to the murder.
