The investigation included concerns of "cuckooing" in the town, which can potentially be connected to "County Lines" drug crime.
"County Lines" refers to drug dealers from large cities who expand their operations into smaller towns.
They endeavour to exploit young and vulnerable people to sell drugs, carry cash and weapons – bringing violence, coercion and abuse.
They may also take over a vulnerable person’s house – known as "cuckooing".
Constable Christopher Cran, from the Community Policing Team in Fraserburgh, said: "This type of behaviour will not be tolerated within north east communities or by the police.
“I would urge anyone with information or concerns in relation to drug-related criminality to contact us.
“There are support services through local authorities that can help victims and prevent them becoming repeat victims of individuals who target vulnerable people."
