Two Leavesden homes were raided by police cracking down on drug dealing early on Friday morning.
A warrant was executed by Three Rivers officers in Curtiss Drive at around 7am, where suspected class A and B drugs were seized.
An 18-year-old man was arrested on suspicion of possession of a class A drug with intent to supply and has since been released on police bail.
At the same time in Cheshire Drive, another property was broken into by police and a 24-year-old woman was given a warning after a small amount of cannabis was discovered inside.
Three Rivers Chief Insp Catherine Akehurst said: “We are committed to tackling drug related crime in the district and will pursue anyone believed to be involved.”
Call 101 if you have information or suspect drug dealing may be taking place in your area.
