Officers carried out a warrant at an address in Ladybrook Place in Mansfield just after 4.30pm on Friday 30 June.
Entry was forced through the front door where a group of people were found congregating in the living room.
A search of the property found a large quantity of cash, mobile phones, and suspected Class A drugs (heroin).
A strip search of one of the suspects found a large quantity of brown wraps in his underwear.
Police then located a large amount of cash stuffed in the sofa where one of the suspects was sitting.
Another suspect had a large amount of cash in his sock.
Weighing scales, an extendable baton and flick knife, and a bag of cannabis were also found during the search.
Two other warrants were executed in Layton Burroughs on June 29 where officers searched for evidence of drug supply. There were no seizures but an ongoing investigation is underway around both addresses.
Sergeant Alice Bartle, from Mansfield Central Neighbourhood Policing Team, said: “This was a great result by officers who have removed a significant amount of suspected heroin and cash from this property.
“The community had raised concerns about the activity coming from this address and we have acted upon that intelligence.
“No one should have to live next to a property suspected of dealing Class A drugs and all the anti-social behavior this can cause.
“We are now working on a number of lines of inquiry to build up a better picture of this drugs operation.”
