NEW YORK — Sean "Diddy" Combs headed to jail Tuesday to await trial in his federal sex trafficking case, after a magistrate ordered him to be held without bail in a case that accuses him of presiding over a sordid empire of sexual crimes. The music mogul pleaded not guilty Tuesday to racketeering conspiracy and sex trafficking. He's accused of inducing female victims and male sex workers into drugged-up, sometimes dayslong sexual performances dubbed "Freak Offs.

" The indictment against him also refers obliquely to an attack on his former girlfriend, the R&B singer Cassie, that was captured on video. Prosecutors wanted him jailed. His attorneys proposed that he be released on a $50 million bond to home detention with electronic monitoring.

U.S. Magistrate Judge Robyn Tarnofsky sided with the government.

"Mr.Combs is a fighter. He's going to fight this to the end.

He's innocent," his lawyer, Marc Agnifilo, said after court. He said he would appeal the bail decision. The Bad Boy Records founder is accused of striking, punching and dragging women, throwing objects and kicking them — and getting his personal assistants, security and household staff to help him hide it all.

Federal prosecutors called him dangerous. "Mr.Combs physically and sexually abused victims for decades.

He used the vast resources of his company to facilitate his abuse and cover up his crimes. Simply put, he is a serial abuser and a serial obstructor," Assistant U.S.

Attorney Emily Johnson told a court. Sh.
