Gardai have identified the man found dead in suspicious circumstances near Dunboyne, Co Meath last Sunday.
They have named him as 36-year-old Grazuydas Strelciunas from Lithuania. A man and a woman remain in custody in Blanchardstown and another woman is in custody in Ashbourne in connection with the investigation into Mr Strelciunas's death.
The gardai had been waiting for assistance from his family to confirm the identification. The motive for the apparent attack on him is still unclear.
Mr Strelciunas was found dead just before 5 p.m. last Sunday in a remote area at Walterstown, Dunboyne. From his injuries, it appeared he had been beaten before he died.
