A massive drugs raid in Port Glasgow saw police seize almost £1million worth of cannabis.

More than 600 plants and high-tech equipment including filters were picked up by officers at a unit on Muirshiel Road.

The huge haul is believed to have a street value of £985,400, according to the Greenock Telegraph.

Police have confirmed they are now hunting the persons involved.

It is understood the drugs were seized after a member of the public called cops about a "strong pungent smell" coming from the area.

Inspector Julie MacDonald said: "This substantial recovery emphasises our commitment to disrupting drug activity and local supply.

"Drugs cause real devastation to our communities and families. Police Scotland will continue to target anyone involved in drugs and the criminality that surrounds it.

"This recovery originated from an observant member of the public coming to us with information that allowed us to act."

Anyone with concerns or information regarding the cultivation or drugs in their area is asked to contact 101 or alternatively get in touch with Crimestoppers on 0800555111 anonymously.
