A murder inquiry has been launched after a man shot several times at a family wedding reception died in hospital.
Two suspects arrested over the gang-related shooting of 21-year-old Robert Sheehan remain in custody.
The victim was shot in the head and upper body about five times in the attack at Bunratty Castle Hotel in Co Clare.
Gardai said the shooting occurred in the grounds of the hotel at about 4am on Sunday when Sheehan went outside for a cigarette. A gun was recovered near the scene.
Gardai said two men involved in the fatal shooting were seen fleeing in a black car which had been waiting in the hotel grounds.
It is understood the victim was approached and shot several times at close range.
In a follow-up operation, two suspects, both in their 20s, were detained in Cork city several hours after the attack.
The men were being questioned at Mayfield and Gurranabraher Garda stations in the city under section 50 of the Criminal Justice Act.
The pair can be held for seven days under the legislation introduced in 2007, in part, for the investigation of gun murders and organised crime.
It is understood Sheehan was attending a family wedding at the hotel when he was attacked. He is from the Moyross area of Limerick.
