The shooting of three people outside a Dublin pub owned by an international footballer may be linked to a turf war by door security firms, detectives have signalled.
A doorman shot in the head at The Players Lounge, run by Ireland and Hibernian striker Anthony Stokes's family, is believed to have been the prime target.
Two bystanders caught up in the attack were hit in the chest and the back.
The doorman, Wayne Barrett, 31, from Finglas, north Dublin, was critically injured and is fighting for his life at Beaumont Hospital.
The other victims, one in his 20s and the other in his 30s, are being treated at the city's Mater Hospital.
One is described as critically ill and the other seriously injured.
The pair were thought to be among customers having a cigarette outside the pub in Fairview when the lone gunman opened fire at around 12.30am early on Monday morning.
Detectives believe the attacker may have fired from two handguns before making off in a car found burnt out shortly after the attack in Dublin's south inner city.
One line of inquiry is that the shooting could be linked to a row between organised criminals and former Provisional IRA members over who controls door security in the area.
But a senior Garda source stressed: "It could be down to an individual row as well. There are always rows in bars."
