GARDAI have recovered a knife which they believe was used in a frenzied attack on a homeless man, who died from his wounds.
The murder victim was named last night as Jacek Kozakiewicz, a Polish man (43), who had been squatting with others in a derelict pub at North Wall Quay in Dublin's docklands.
Gardai believe a row erupted while a group of four men and a woman were drinking in the former Vallance and McGrath premises at New Wapping Street on Wednesday night.
Officers were alerted after another man, who had blood on his hands and clothing, knocked on the driver's cab on a Luas tram at the O2 stop shortly before 11pm. Gardai were called, and after interviewing the man they went to the derelict premises, where they found two men with serious injuries lying on the ground on the third floor.
Mr Kozakiewicz was pronounced dead after a medical examination while a 28-year-old man, named as Filip Talaj, was taken by ambulance to the Mater Hospital, where he was treated for a fractured skull.
He was recovering from his injuries in hospital last night after receiving a number of stitches in his head wounds.
Meanwhile, gardai arrested a 36-year-old man for questioning about the attack. He was taken to Store Street garda station, where he was being held last night under section 4 of the Criminal Justice Act.
The derelict building was sealed off, pending the completion of a forensic examination of the third floor and a knife, found on the premises, was taken away for detailed checks to be conducted.
A post mortem examination on the body of the murder victim got under way last night after the office of the State Pathologist had been contacted.
Gardai said it was not clear from a preliminary examination how many times he had been stabbed, but said all of his wounds appeared to be to the upper body or neck.
Last night officers were continuing to interview a number of people as they tried to piece together the circumstances leading up to the stabbing.
But they said the row appeared to stem from a relatively minor argument while the group were drinking.
