A local councillor and residents had called for more action against offenders in the Plungington area.
And yesterday neighbourhood officers met residents in the area to listen to their concerns.
Photographs were posted on social media earlier this month of a house in the Plungington area plastered with notices.
Some read: “Drugs sold here”, “Drug dealers live here”.
Plungington Labour Coun Pav Akhtar said drug dealing and anti-social behaviour was a major issue in the area.
He said the notices on the suspected drugs den were a sign that people may soon take matters into their own hands.
Police responded to the concerns by sending officers to the area.
A meeting was then arranged at the local SPAR where residents could speak directly to officers.
Coun Akhtar said yesterday : “I’m just glad that the community is being listened to and I feel assured that the police are serious about getting action to clean up our community.”
He said drug dealers and sex workers were a regular sight in the area.
In an earlier tweet he thanked the neighbourhood team and added: “Good to know arrests were made. One brothel and a drug den closed. Some more to go.”
A Lancashire police spokesman confirmed that two youths had been detained but released.
He said officers would take action to address issues raised by the community.
