Gardaí in Cork are treating as murder the death of 20-year-old student Cameron Blair, who was stabbed at a house party in the city last night.
A post-mortem examination on Mr Blair's body has been completed at Cork University Hospital.
Further results from the post-mortem examination aren't being revealed.
Cameron, who was a second-year student at Cork Institute of Technology, was from the village of Ballinascarthy in west Cork.
He is survived by his parents and younger brother.
Cameron is understood to have been at a party in the house he lived in on Bandon Road last night when a dispute arose at around 9.10pm, during which he was stabbed.
He staggered out onto the street before he collapsed.
He was treated at the scene before being taken to Cork University Hospital where he was later pronounced dead.
Around 20 people were in the house at the time.
It is understood a group of people arrived at the house shortly after 9pm and a dispute arose as they were refused entry.

The young man was stabbed and his attacker fled the scene.
Many students from CIT and nearby University College Cork live in the Bandon Road area and the street was busy last night when the stabbing occurred, as students returned from the Christmas break.

"Students are being cared for and counselled in school. Classes continue for all year groups as we try to keep the school day as normal as possible, while recognising the traumatic impact on many."
