Gardaí are continuing to study thousands of hours of CCTV footage as part of their investigations into the discovery of a man's dismembered body in Dublin's Royal Canal two weeks ago.
The body of a black male, aged in his 20s or 30s, was found in water at two locations close to Ballybough bridge.
Gardaí have taken CCTV tapes from within a mile radius of the bridge and are going through tapes for the month of March 'frame by frame' in a bid to identify the man's killer or killers.
It is believed the man may have been killed a number of weeks before his body was found in the canal. The man's head has not been found.
Gardaí are actively investigating the possibility the man was the victim of a so-called ‘ritual killing’, but stress they are considering other lines of enquiry.
Gardaí say it is possible the man was killed at a location outside of the Dublin area, and stress their appeal for information is nationwide. The man's body will remain at Dublin City Morgue until he is identified.
Detectives are liaising with British police, Europol and other police forces in a bid to identify the man. A search of fingerprint databases has so far failed to establish his identity.
Detectives say they have received an excellent response to last weekend's appeal where a reward was offered by Irish Crimestoppers for information leading both to identifying the man, and to finding the location where he was actually killed and his body dismembered.
Officers at Fitzgibbon Street are following up a number of sightings of black males wearing white coloured Ireland away soccer jerseys. Such a long sleeved, large sized jersey was found with the man's torso.
Gardaí are appealing for anyone with information to contact them on Freephone 1800 218 219.
