Sean Combs, Music Mogul Known as Diddy, Denied Bail on Sex Trafficking Charges

Sean Combs, the embattled music mogul, was denied bail on Tuesday after pleading not guilty to charges of sex trafficking, racketeering conspiracy and transportation to engage in prostitution.

In a federal indictment unsealed on Tuesday, Mr. Combs, 54, was described as the boss of a yearslong criminal enterprise that threatened and abused women, coercing them to participate against their will in drug-fueled orgies with male prostitutes and threatening them with violence or the loss of financial support if they refused.

The 14-page indictment against Mr. Combs, a producer, record executive and performer who is also known as Diddy and Puff Daddy, came a day after he was arrested in a Manhattan hotel room, following an investigation that has been active since at least early this year. Prosecutors said Mr. Combs and his employees engaged in kidnapping, forced labor, arson and bribery, and kept firearms at the ready.

In asking a magistrate to deny Mr. Combs’s request to be released on bail, prosecutors argued that he was a threat to the community. One of the prosecutors, Emily A. Johnson, called him a “serial abuser and a serial obstructer,” and said his wealth would make it easy for him to escape undetected. She noted that after Mr. Combs was arrested, law enforcement found what they suspected to be narcotics in his hotel room, in the form of pink powder.

Mr. Combs’s lawyers suggested a $50 million bond. But Judge Robyn F. Tarnofsky denied their request, citing Mr. Combs’s anger issues and history of substance abuse, and ordered Mr. Combs detained while he awaits trial.

“My concern,” the judge said, “is that this is a crime that happens behind closed doors.”

As Mr. Combs walked out of the courtroom, he looked toward his supporters in the room, including his three adult sons, and put his hand on his heart.
