Police said in a statement obtained by The Irish Times that "human limbs were found in a bag outside houses at the junction of Moatview Gardens and Drive".
The Dublin City Coroner has been notified, and the services of the State Pathologist have been requested.
The scene was secured overnight and this morning it was examined by the Garda Technical Bureau.
Officers say they will look for assistance from Forensic Science Ireland to help identify the remains.
Gardaí are awaiting DNA tests to confirm the identity of the victim, amid fears they may be that of a missing 17-year-old boy from Drogheda, Co Louth.
Detectives are said to be investigating the possibility that the missing teenager may have been brought to the location and attacked there. Local officials suspect the remains are linked to rising drug crime in Dublin and surrounding towns.
