The death of a man whose body was found in the living room of his rented house in Skibbereen early on Monday morning is now being treated as murder by gardaí.
A post-mortem examination has been carried out on the body of 51-year-old Englishman John Ustic by State Pathologist Dr Marie Cassidy.
Following the release of results to gardaí last night, the inquiry has now been designated a murder investigation.
Superintendent Ger O'Mahony, who is leading the investigation, said it was clear that Mr Ustic died as a result of an injury sustained in an assault.
However, he declined to give further details for operational reasons.
An incident room has been set up at Skibbereen Garda Station, and a full investigation team is in place.
Gardaí have already begun making door-to-door inquiries, examining CCTV footage from local businesses, and interviewing witnesses who responded to yesterday's appeal for information.
Superintendent O'Mahony said they were very pleased with the number of people who have contacted gardaí but again asked anyone with any information regarding Mr Ustic's movements on Sunday to contact them.
The alarm was raised when the deceased was found by his partner in the living room of their rented, terraced house at High Street in Skibbereen, at around 9am yesterday.
It is understood Mr Ustic was last seen in a nearby car park on Sunday evening when he was found by neighbours with bruises and cuts, and brought home.
The car park, which is adjacent to the garda station, and opposite Mr Ustic's home, had been sealed off for forensic examination but has now re-opened.
Members of the Garda Technical Bureau who travelled from Dublin are still carrying out a detailed forensic examination of the rented house.
