Three people have been arrested following a day of action targeting suspected drug supply networks on Anglesey.

Officers carried out four warrants at properties in the Valley and Holyhead areas on Thursday following intelligence gathered by North Wales Police’s Neighbourhood Policing Team.

The operation resulted in three arrests in connection with the suspected supply of illegal drugs. All three have since been interviewed and released under investigation while enquiries continue.

Police also seized quantities of substances believed to be cocaine and cannabis.

PC Andrew Jones said the action followed concerns raised by local residents about the supply of cocaine and ketamine within the community.

He said: “These results come after community concerns about the supply of cocaine and ketamine in the area.

“People who bring drugs into our communities do not care about the pain and misery they cause, only the profit they can make from exploiting vulnerable people.

“We thank members of the public for their continued support and information that helps us to take drugs off the streets of Anglesey.

“We encourage residents to continue to come forward with any concerns around drug supply in their community and we will fully investigate information received.”

The operation highlights the ongoing battle being fought by police forces across North Wales against illegal drugs and the organised criminal networks that profit from them.

While cocaine remains one of the most commonly seized Class A drugs in the region, officers have also expressed concerns in recent years about the increasing availability of ketamine, a drug often associated with younger users but which can have serious long-term physical and mental health consequences.

Police and support agencies warn that drug misuse can have far-reaching effects beyond individual users. Communities can experience increased anti-social behaviour, violence, exploitation, theft and intimidation linked to drug markets. Organised crime groups are also known to target vulnerable adults and children through practices such as county lines drug trafficking, where young people are recruited or coerced into transporting and selling drugs.

North Wales has seen a number of high-profile prosecutions involving organised drug supply networks in recent years, with courts repeatedly hearing how illegal drugs have fuelled addiction, family breakdown, crime and significant pressures on health and support services.

Local authorities, health organisations and charities continue to work alongside police to tackle both the supply of illegal drugs and the underlying issues that can make people vulnerable to addiction, including poor mental health, social isolation and poverty.

North Wales Police is urging anyone with information about suspected drug activity in their area to come forward. Information can be provided directly to the police or anonymously through Crimestoppers.
