A man has been arrested in connection with the death of 22-year-old Mahamud Ilyas, whose body was found in a field in Co Meath over the weekend.
A house in Dublin 15 has also been sealed off and a technical examination is under way.
The man in his 50s was arrested in Dublin and is being held at Blanchardstown Garda Station under Section 4 of the Criminal Justice Act.
Mr Ilyas was attacked and beaten to death before an attempt was made to hide his body.
He was wrapped in heavy material, driven to Kilbride, a remote rural area near the Dublin-Meath border and carried on to lands at Belgree Lane where his body was left in a copse of trees.
