Two men have been arrested over the gang-related attempted murder of a man at a wedding reception.
The 21-year-old, named locally as Robert Sheehan, was shot in the head and upper body about five times in the attack at Bunratty Castle Hotel in Co Clare.
Gardai said he is in a critical condition in hospital.
The shooting occurred in the grounds of the hotel at about 4am when Sheehan went outside for a cigarette. A gun was recovered near the scene.
Gardai said two men involved in the shooting were seen fleeing in a black coloured 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 aged in their 20s, were detained in Cork city.
The men were being questioned at Mayfield and Gurranabraher Garda stations 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.
