The home of businessman Sean Quinn has been searched by Gardaí in Co Cavan.
Officers in the Cavan/Monaghan division executed a search warrant issued by a District Court judge.
The search at the residence began at around 11.00am Wednesday morning, and was completed about two hours later in the early afternoon.
No arrests have been made.
Gardaí say the search was in connection with alleged criminal activity in the county and wider border region.
Irish Times crime correspondent Conor Gallagher told The Hard Shoulder officers left the property with a number of items.
"Gardaí were seen leaving the property with a number of boxes, and it's understood that they have taken away boxes of documents and some electronic devices.
"The search was carried out, according to a statement, by Gardaí by officers from the Cavan/Monaghan division following the issuing of a warrant from a District Court judge under Section 10 of the Criminal Justice Act.
"Section 10 allows for Gardaí to enter premises to search for evidence when investigating particularly serious offences."
Conor says the businessman has been speaking about what happened to the BBC.
"Mr Quinn himself confirmed that the Gardaí had searched the home, and spent about 90 minutes inside looking around.
"Sean Quinn says he was told... by Gardaí that it was relating to 'coercion, deception, harassment - stuff like that' he said.
"He said the Gardaí gave him very little information and said to just let them get on with their investigation.
"He said they never mentioned anything about criminality - Mr Quinn called it a 'fishing expedition' because the Gardaí wouldn't, or couldn't, say to them why they were there".
