A 64-year-old publican has been found dead in Daingean near Tullamore in Co Offaly.
The man has been named locally as Matt Farrell.
Although it has not been confirmed if anything is missing from the property, gardaí have said his death has all the hallmarks of a robbery gone wrong.
His body was found in his home, which adjoins the pub.
He was last seen alive at the pub at around 2.30am and was found tied to a chair by one of his two sons at around 7.30am.
Gardaí said he was the owner of the pub and lived on the premises on Main Street in Daingean.
Mr Farrell was the father of four children.
He had been working in the area for more than 30 years as a publican.
The death is being treated as suspicious and Deputy State Pathologist Dr Michael Curtis is due at the scene later.
Garda forensic crews have been at the house since early morning.
Up to 100 gardaí are now involved in the investigation.
