Sean “Diddy” Combs was ordered held in custody Tuesday pending trial after pleading not guilty to charges including sex trafficking and racketeering.

On Tuesday morning, authorities unsealed a three-county indictment charging Combs with multiple crimes related to an alleged decades-long pattern of physical and sexual violence against women in his community. Federal prosecutors charged him with sex trafficking and racketeering for running a vast criminal enterprise through which he assaulted and trafficked women using his various businesses beginning at least in 2008.

“I am concerned that this is a crime that is happening behind closed doors,” Judge Robyn Tarnofsky said, referring to the sex trafficking allegations and more, as she announced her decision to deny bail pending trial. The judge added that she was concerned about a power imbalance between the mogul and the alleged victims and that those alleged victims could be susceptible to coercion.

Combs’ attorneys said at a press conference after the hearing that they would appeal the decision to hold Combs without bail. They were scheduled to return for a hearing on Wednesday.

Combs attended Tuesday’s hearing dressed in a black T-shirt and sweatpants. A row of family members, including several of his children, sat behind him in the packed gallery. Combs did not speak aloud, except to say he was not guilty, but he nodded frequently in agreement with his attorney, Marc Agnifilo, as he discussed the measures Combs had taken to cooperate with law enforcement.

Combs asked to be released on $50 million bail, secured by equity in his Miami home and that of his mother. He proposed being placed on house arrest with GPS monitoring and restricted to parts of Florida, New York and New Jersey, primarily to handle pending court cases and attend medical appointments.

Agnifilo added that he had obtained the passports of Combs and several family members months ago and that Combs was in the process of selling his private jet to alleviate fears of flight risk. He noted that Combs also voluntarily flew to New York on Sept. 5 to await arrest. While in New York, Combs sought counseling and treatment, he said.

“We can trust him because he has earned his trust through actions,” Agnifilo said.

The government opposed bail, saying he poses an ongoing security risk and may attempt to tamper with the case or flee.

“He is a serial abuser and a serial obstructionist,” said Assistant ADA Emily Johnson.

The indictment alleged that Combs repeatedly committed violent acts, including assault, arson and brandishing firearms. In December 2011, for example, he and an associate kidnapped an unnamed individual at gunpoint to burglarize a home, according to a criminal complaint filed by prosecutors. About two weeks later, members of the alleged criminal enterprise set the individual’s car on fire with a Molotov cocktail.

It is believed to be Kid Cudi, who confirmed in a lawsuit allegations by Casandra Ventura, better known as Cassie, that Combs set the rapper’s car on fire.

Prosecutors highlighted Combs’ access to firearms. During a March raid on his home, law enforcement seized several weapons, including three AR-15 rifles, each with illegible serial numbers, the complaint said.

The government said Combs has a “propensity for violence,” which makes him ineligible for release. “No bail conditions can address the defendant’s propensity to become violent when angry or emotional; anyone in his presence is at risk of assault or sexual assault,” the filing said.

Prosecutors also opposed bail, arguing that Combs is likely to obstruct the proceedings, alleging that he bribed hotel security to prevent them from releasing video of his attack on Ventura.

More recently, Combs and his associates allegedly contacted potential witnesses in the investigation and instructed them to lie in an attempt to cover up his alleged crimes. During one of the calls, which occurred just three days after he left Ventura, the mogul allegedly asked about the victim’s “friendship” and told her she had “nothing to worry about” if she followed his version of events.

In addition, the government alleged that Combs poses a significant flight risk because of his substantial resources. They said he has access to dozens of bank accounts, some personal and many corporate, containing millions of dollars, as well as more than $1 million in personal cash on hand.

If Combs “wanted to flee, he has the money, manpower and resources to do so quickly and undetected,” the filing said. Prosecutors also emphasized the seriousness of the charges as a reason for Combs to flee.
