Gardai in Dún Laoghaire, Co Dublin, are appealing for witnesses to the shooting of three nightclub doormen in Adelaide Road last Friday night.
The attacker, who was wearing dark clothing and a black balaclava, opened fire on the men with a shotgun in each hand. He fled by car in the direction of Mellifont Avenue. They were taken to St Michael's Hospital, Dún Laoghaire, where their injuries were said to be not life-threatening.
In a separate investigation a man in his early 20s who was arrested in connection with the stabbing of another man in Swords, Co Dublin, was released yesterday. A file is being prepared for the DPP.
The stabbing occurred in the main street at around 2.15 a.m. yesterday. The injured man, in his 20s, who was stabbed in the head, was taken to Beaumont Hospital. His condition is not serious.
Meanwhile, the Archbishop of Dublin, Cardinal Desmond Connell, has expressed deep concern at what he described as "the rising tide of almost casual violence in our city and the growing contempt for the inviolability of human life".
Speaking at a Mass to celebrate the 80th anniversary of the foundation of the Garda Síochána, he said the murder of a Chinese student, Mr Zhao Liu Tao, was "a brutal expression of something which calls for special concern, racial tension and intolerance."
He said: "Unfortunately, there would seem to be increasing violence even to the excess of murder. I think of the murder of Zhao Liu Tao, the murders associated with the drug culture and the injuries caused by callous aggression.
"Here I think especially of Guido Nasi [the Italian student paralysed after an attack in a north Dublin park in 1999]."
