A father and son have been arrested in connection with the investigation into the murder of Kilnaleck Detective Garda Adrian Donohoe, the Irish Independent reports.
The two are thought to be associates of the gang that gardaí believe murdered Det Garda Donohoe four weeks ago today at a credit union in Lordship, Co Louth, a mile from his home.
Gardaí believe they are linked to a group who may have supplied the stolen Volkswagen Passat that was used by the gang in their getaway from the scene.
That car had been stolen from Clogherhead, Co Louth, days before the murder.
Car 'ringers', the paper says, have been involved in vehicle thefts on both sides of the Border in counties Louth, Monaghan, Armagh and Down for years and operate from the Dundalk area.
The men, in their 30s and 70s, are believed to be operating close to the 'ringers' and were arrested early yesterday morning (Thursday, February 21).
They were taken to Drogheda Garda Station for questioning under section 30 of the Offences Against the State Act and can be held without charge for up to three days.
