A boy has been arrested after MDMA worth €600,000 was uncovered during searches in Dublin.

The discovery was made at a house in Lucan after a planned operation involving Gardaí and Revenue officials.

A “juvenile” was arrested at the scene and taken to Ronanstown Garda Station.

He has since been released without charge and Gardaí say a file will now be prepared for the DPP.

The investigation is ongoing.
