A man arrested in connection with the disappearance and murder of Kyran Durnin has been released without charge.
Gardaí yesterday arrested a man on suspicion of murdering the Co Louth schoolboy.
The 8-year-old has not been seen in more than two years and is believed to have been murdered when he was six years old.
A major search has been carried out this week at a property and its adjoining gardens at a housing estate in Drogheda, Co Louth.
Gardaí say the details of this search operation are not being released for operational reasons.
A woman arrested on Tuesday was also released without charge.
