A Belltown nightclub was raided this week after a months-long drug trafficking investigation.
Police started investigating Foundation Nightclub in March after reports of drug dealing and sexual assault inside the club.
Authorities said undercover cops from Seattle Police and Homeland Security purchased cocaine, methamphetamine, and date rape drugs like GHB from management employees.
The Seattle Police Department's Detective Patrick Michaud said the in-house dealers were not always discreet.
"One dealer even bragged about knowing the owner and later told our undercover officer how much GHB to use to dose women depending on their weight,” Michaud said.
Twelve people were arrested Wednesday.
Drugs, two handguns, and $60,000 cash were confiscated.
The state liquor board has suspended Foundation's license and the club said on Facebook they will close during this investigation.
