Cannabis resin with an estimated street value of over half a million euro has been seized in west Dublin.

Gardai from the Ballyfermot Drugs Unit found the drug during a search of a house in the Cherry Orchard area this morning.

The search was part of an ongoing investigation into the sale and supply of controlled drugs.

A man in his thirties was arrested at the scene - he's being held at Ballyfermot Garda Station under Section 2 of the Criminal Justice (Drug Trafficking) Act, 1996 at Ballyfermot Garda Station. He can be held for up to 7 days.

Gardai say enquiries are continuing.
