Sean ‘Diddy’ Combs is now a criminal defendant in a sex trafficking, racketeering and kidnapping case after a grand jury indicted him … this according to official documents.

Diddy has been charged with 3 counts — racketeering conspiracy, sex trafficking by force, fraud or coercion, and transportation to engage in prostitution.

According to the indictment, from 2008 to the present, members of the Combs enterprise allegedly engaged in sex trafficking, forced labor, interstate transportation for purposes of prostitution, coercion and enticement to engage in prostitution, narcotics offenses, kidnapping, arson, bribery and obstruction of justice.

According to the indictment, the purpose of the Combs enterprise was to operate a global business in the media, entertainment, and lifestyle industries. The purpose also includes preserving Diddy’s power and fulling his personal desires, especially relation to his sexual gratification, including through the exploitation of women and the use of commercial sex workers.

The indictment mentions the now-famous freak off parties … calling them “elaborate and produced sex performances that Combs arranged, directed, masturbated during, and often electronically recorded.

The indictment alleges Combs lured women into his orbit under the pretense of a romantic relationship and then used force, threats of force, and coercion, to cause victims to engage in extended sex acts with male commercial sex workers.”

After the freak offs, Combs and the victims typically received IV fluids to recover from the physical exertion and drug use.

The indictment does not include details on the kidnapping allegations, other than they occurred in California.

His lawyer, Marc Agnifilo, said going into the courthouse, he will “fight like hell” to get his client released on bail. Agnifilo said his client is not only not guilty, but outright innocent.

Diddy will appear before a judge Tuesday morning where the charges will be read.

TMZ broke the story … Diddy was arrested Monday night at the Park Hyatt hotel in midtown Manhattan, where he had been staying. Law enforcement sources told TMZ … the arrest was supposed to go down Tuesday but something happened to accelerate it.

Aubrey O’Day, who had a contentious relationship with Diddy during filming of “Making the Band,” tells TMZ, “I never thought I would see this day. We all buried this inside of us in order to be able to keep going. And not just me, but victims you don’t even know yet. We are all processing what that type of vindication can actually feel like now. Every conversation I’ve had with victims last night has been beyond moving on all levels.”

30 minutes before the arrest, Diddy was outside the hotel chatting it up with fans.

Hours before the arrest, he was walking with his son Christian ‘King’ Combs on the streets of New York.
