Armed police who surrounded a house in the hunt for a murder suspect have stood down the operation after establishing the property was empty.
Garda officers had sealed off the area in Burnfoot, Co Donegal amid concerns 58-year-old Londonderry man Kieran McLaughlin was holed up inside.
Mr McLaughlin has been identified by police in Northern Ireland as a suspect in the murder of 35-year-old Barry McCrory in Derry on Thursday.
Gardai, who have been providing assistance to their counterparts from across the border, had been focusing on the property through Friday evening and into Saturday morning.
Burnfoot is only a short distance from Londonderry, around five miles (8 km) across the Irish border.
A Garda spokesman confirmed the operation had been stood down with no arrests made.
Mr McCrory was gunned down in a flat in Derry city centre on Thursday morning.
His partner, who was in the Shipquay Street property at the time, was bundled into another room by the lone killer before the fatal shots were fired.
It is understood the incident related to a fallout over alleged criminality.
Mr McCrory had been known to police for previous offending.
Police have warned people not to approach Mr McLaughlin.
The murder took place less than 24 hours after the body of a father-of-four was found in a lake in north Belfast.
It is understood Kevin Kearney, 46, was shot dead by dissident republicans. A 39-year-old man has been arrested in connection with the shooting.
Officers are not linking the two murders at this stage.
