Gardaí investigating the murder of a man, whose dismembered body was found in Dublin's Royal Canal in March, have arrested three women and a man.
They have also identified the man as Somalian national Farah Swaleh Noor (38) who had been living in Ireland since 1996.
A 49-year-old woman with addresses in Phibsboro and Tallaght, was arrested in Summerhill at 10.15am while a 22-year-old woman from Tallaght was arrested at 10.40am in Tallaght. Both were taken to Mounjoy Garda station. A 30-year-old Tallaght woman was also arrested at 10.40am and taken to Store Street station. The 52-year-old man from Tallaght was arrested in Terenure at 10.55am and also taken to Store Street.
The four, who are all Irish, have had their detention period extended for a further six hours.
Gardaí have appealed to anyone who knew Mr Noor or were in the Ballybough, Royal Canal or Richmond Cottage areas on March 29th and 30th last to contact the incident room at Fitzgibbon Street Garda Station on 1800 218 219.
After the discovery of Mr Noor's dismembered and headless remains gardaí said the man died a "brutal" death. The man had been dead for more than a week before his torso was discovered partially wrapped in black plastic in the canal. He had been decapitated and had his legs and arms severed and had been stabbed a number of times.
Officers believe he was killed elsewhere before being dumped in the Royal Canal near Croke Park and were anxious to identify the original murder scene.
The remains were discovered at the same stretch of the canal, near Ballybough Bridge in the north inner city, where the badly beaten body of a Romanian man, Adrian Bestea, was found stuffed into a suitcase in 2001.
