A fourth man has been arrested after a large haul of drugs was found in Blaenau Ffestiniog.
Two men from Liverpool and a third from Gwynedd were questioned on Wednesday following the raid at an undisclosed address in the town. They’ve been released on bail but remain under investigation.
Detectives said a local man was arrested on Friday for being involved in the supply of controlled drugs – a fresh batch of Class B drugs was also seized.
Caernarfon magistrates have also granted police permission to close the premises raided.
District Inspector Matt Geddes said the closure order would safeguard the local community ”from having to endure any recurrence of the circumstances leading up to this police action.”
He added: ”We will continue to work hard with the community to identify and arrest those involved in serious and organised crime, who cause such harm to our society.”
A large haul of class A controlled drugs and cash was discovered in Wednesday’s raid, following tip-offs from the public.
