A man has been left fighting for his life after being shot four times in an attack at a gym on an industrial estate.
Sean Enright, who survived a previous attempt on his life in 2011, was attacked outside the fitness centre on the Ballyboggan industrial estate in north Dublin.
Gardai said the victim, a champion bodybuilder believed to be in his early 30s, suffered several gunshot wounds to the upper body.
The attacker is believed to have fled the scene in a silver BMW Mini which made off in the direction of Finglas, gardai said.
Officers in Cabra are investigating.
Mr Enright was attacked at the Universal Warrior gym, which he operates with associate JJ Dunne, at about 10.40am.
The silver Mini used as a getaway car had northern registration plates, gardai said.
Shell casings and two black sports bags could be seen at the entrance to the warehouse-type fitness centre where the shooting was carried out.
Mr Enright has undergone emergency surgery in the Mater Hospital in Dublin, where his condition is described as critical.
He survived a gun attack in January 2011 when he was shot several times as he sat in a car outside a house in Clonsilla, west Dublin.
He was also reportedly living under a death threat.
The Ballyboggan industrial estate has dozens of businesses and is located just off Ballyboggan Road, about 9km (5.6 miles) from the city centre.
The estate remained open following the shooting, with a car park in front of the gym sealed off by gardai.
The shooting follows a separate attack in Swords, north Dublin, yesterday when a man escaped uninjured in an attempted murder as he was leaving a gym.
It is understood the attacker's gun jammed in the incident.
