Cannabis with a street value estimated at more than €500,000 has been seized by gardaí in Co Cork.

A man has been arrested and is being questioned in connection with the seizure.

The drugs were seized following a search at a house at Tarelton near Macroom.

The seizure is part of a garda operation which has resulted in the discovery of five cannabis grow houses and the seizure of a small quantity of cocaine in the area in recent weeks.

Three other people have been arrested as part of the garda operation.
