Four houses in Cork city have been searched this morning by gardaí investigating the murder of former Real IRA leader Aidan O'Driscoll.
The searches are focused on three houses on the northside of the city and one on the southside.
Up to 30 gardaí are involved in the searches, which are focused on gathering information to progress the investigation into the December 7 slaying of the father of two on Old Commons Road in Blackpool.
No arrests have been made as part of the this morning's operation.
The searches, which are ongoing, are being coordinated from Watercourse Road garda station.
The operation follows the recent arrests of six people in the city and Blarney for questioning about the murder.
The six were all released without charge and six individual files are now being prepared for the DPP.
Gardai said in the wake of those arrests that there were more in the pipeline.
Aidan O’Driscoll, who had been due to marry his fiancée next month, had lived for periods in Limerick and Dublin.
Gardaí are focused on a falling out with old associates in Cork as a motive for the gunning down of the Ballyvolane father of two. He was on his way to a painting and decorating job in a nearby house when he was gunned down just before 5pm on December 7 on the Old Commons Road. He had just been dropped off by work colleagues minutes before.
