Last month, officers launched an operation after identifying a phone line being used to sell cocaine in the Kent town after enquiries that linked activity across Dartford and south London.
Search warrants were executed on Monday (May 18) at addresses in all three areas, where police arrested four people and seized suspected heroin and cocaine, along with cash and mobile phones.
Lily Freel, 26, and Tyler Lamptey, 20, both of Cranfield Road in Lewisham, have since been charged with being concerned in the supply of Class A drugs.
Lamptey was also charged with possession of class A drugs.
Both appeared at Sevenoaks Magistrates’ Court on Tuesday (May 19).
Lamptey was remanded in custody to appear at crown court at a later date, while Freel was released on bail to appear at Maidstone Crown Court on June 15.
A 20-year-old woman from Dartford and a 28-year-old woman from London were also arrested on suspicion of being concerned in the supply of class A drugs.
Both have been released on bail pending further enquiries.
