North Wales Police officers, working closely with Cartrefi Cymunedol Gwynedd, have conducted a search warrant at 25a Dean Street Bangor, following concerns raised by the local community and businesses.
Following the warrant, officers have used powers under the Anti Social Behaviour Act 2003 to close the premises to its occupants and all visitors for 48 hours, from Tuesday 24 September.
North Wales Police will be seeking Court approval to extend this for a period of three months.
Inspector Jon Aspinall said: “This order demonstrates that we have listened to the concerns of those living in neighbouring properties and it sends out a message to those individuals who wish to engage in acts of criminality within the community, that their actions are having a major impact and disrupting the peaceful lives of innocent members of the public.
“We will continue to take action against those who engage in such activity and in doing so, disrupt the lives of others within the community.”
Anyone who has information relating to anti-social behaviour or criminality is asked to contact North Wales Police on 101.
