Four people were arrested on Wednesday (16th of February) after a drugs warrant was executed at an address in the Llannerchymedd area of Anglesey.
As a result of the warrant, which took place at an address in the Lon Cilgwyn area, police seized a quantity of what is believed to be Class C drugs.
Three have since been released on police bail after being arrested on suspicion of drug offences and one has received a police caution. All four are local to the area.
