The Orlando Police Department's Metropolitan Bureau of Investigation has charged 18 people for drug trafficking after a lengthy investigation.

MBI officials say four of those suspects have been on their radar for some time now, and the investigation began in November of 2013.

Several Central Florida agencies worked together for the investigation, and the raid in Orange County.

They believe Kwame King is the leader of the suspected drug trafficking organization.

According to law enforcement, King has been arrested on felony charges 27 times, and four times for misdemeanor crimes.

Police say the majority of the 18 suspects charged have violent criminal histories.

King is facing ten charges related to drug trafficking, and the illegal possession of a firearm.

The organization allegedly used a "stash house" on America Street in Orlando to store cocaine and marijuana before selling it.

Officials found more than 25 pounds of pot and more than 400 grams of cocaine inside the house during the raid.

Investigators say King may be linked to more crimes, and they are pursuing any possible leads to additional charges.

Officials say more arrests are expected.
