A YOUNG man is being questioned about the unlawful killing of a grandfather during a street row after a 60th birthday party.
`The man - who is in his 30s and from the Mahon area of Cork - was arrested for questioning in relation to an alleged assault on Pat 'Patsy' Deasy (57) in the early hours of last Saturday morning.
The man was detained under Section 4 of the Criminal Justice Act and can be questioned for 12 hours.
He was arrested after presenting himself by arrangement at the Bridewell Garda Station in Cork at 9am.
Mr Deasy - a father of four - left the Red Cove pub in Mahon at 12.55am last Saturday to check on the safety of one of his daughters and the condition of his car after realising a confrontation had erupted outside.
Mr Deasy died last Monday in Cork University Hospital (CUH) after failing to regain consciousness from severe head injuries.
It is believed Mr Deasy struck his head on the pavement as he fell - having either been pushed or punched during the street row.
Gardai confirmed they are treating Mr Deasy's death as an unlawful killing but will not release the post mortem results for operational reasons.
Detectives are following a definite line of inquiry in their investigation and said they have been "overwhelmed" with public assistance.
Supt Barry McPolin said while they are pleased with progress they are renewing their appeal for anyone who was on the Avenue des Rennes last Friday night or Saturday morning to contact them.
"We are satisfied that the investigation is progressing well - there has been good co-operation from the public with our inquiries so far," he said.
Crucial to the Garda probe is an analysis of CCTV security camera footage - with footage from a nearby business premises said to be extremely important.
Gardai are also very pleased with a number of eye-witness statements.
