A 50-year-old man has been arrested after a suspected crystal meth laboratory was discovered in Dublin.

Gardaí from the Crumlin Drugs Unit raised a building in Walkinstown and seized drugs worth more than €450,000.

Other items found at the scene include powdered substances, plastic containers, chemical compound, a gas mask, face masks, digital weighing scales, a portable stove, butane gas, plastic funnels and other paraphernalia.

Gardaí were helped in their examination of the scene by a scientist from Forensic Science Ireland, who helped them secure and identify the toxic materials.

The man who was arrested at the scene is being held at Sundrive Road Garda Station and can be detained for up to seven days.
