Sean “Diddy” Combs will remain in federal custody ahead of his trial on racketeering conspiracy and sex trafficking charges after his lawyers failed Wednesday to appeal a judge’s decision to deny him bail.

Prosecutors had argued he was at risk of obstructing the case, and in his ruling Wednesday, Judge Andrew Carter said there were no conditions that reduced the risk of witness tampering or obstruction.

The hip-hop artist is facing charges of racketeering conspiracy, sex trafficking and transportation to engage in prostitution. He pleaded not guilty Tuesday.

Combs, 54, faces a sentence of up to life in prison if convicted. His next court appearance was scheduled for October 9. Combs’ attorney Marc Agnifilo told CNN he will again appeal the ruling.

“I’m not going to let him sit in that jail a day longer than he has to,” Agnifilo said. When asked about Combs’ apparent lack of reaction to the ruling, Agnifilo said: “He’s a stoic guy in his manner. He’s been through a lot in his life.”

Prosecutors allege Combs created and ran a “criminal enterprise” through his business empire that engaged in crimes including sex trafficking, forced labor, kidnapping, arson, bribery and obstruction of justice, according to the federal indictment.

The music mogul was being held by himself at the Special Housing Unit in the Metropolitan Detention Center in Brooklyn, according to a law enforcement official, after another judge denied bail Tuesday.

Prosecutors opposed releasing Combs on any grounds, telling the court he has attempted to tamper with witnesses and saying “the risk of danger is acute.” They pointed to an alleged cache of weapons found in the closet of Combs’ bedroom and his access to millions of dollars in bank accounts and cash that make him a flight risk.

To try to sway a federal judge to release Combs while he awaits trial, his lawyers submitted a new bail package Wednesday that proposed to restrict all female visitors to his home who are not family members and limit all visitors to his Miami properties.

The proposed bail package also included a $50 million bond co-signed by Combs, his mother and several family members; surrender of his passport; home detention; weekly drug testing; and a visitor log to be submitted nightly to pretrial services.

But at the start of Wednesday’s hearing, Carter said the package did not provide reasonable assurance Combs would return to court.

“My bigger concern deals with the danger of obstruction of justice and the danger of witness tampering,” said Carter.

Combs’ attorney proposed putting in place additional “strenuous and maybe unusual conditions” to address the judge’s concerns, including that Combs have no access to a cell phone or internet and to have an intelligence firm staffed with former state and federal officials monitor the residence 24 hours a day. “Any witness intimidation would be completely nullified,” he said in court.

The judge, however, said the package was “insufficient” in ruling the government had met its burden of proof.

Combs’ attorney pushes back against obstruction claims

On Monday night – following a slew of sexual assault lawsuits and a federal human trafficking probe in the past year – Combs was arrested at the Park Hyatt Hotel in Manhattan and taken into custody by Homeland Security Investigations, a source familiar with negotiations for his surrender told CNN.

The indictment states Combs “abused, threatened, and coerced women and others around him to fulfill his sexual desires, protect his reputation, and conceal his conduct” for more than a decade.

Specifically, the indictment accuses Combs of working with other associates and employees, alleges he hosted drug-fueled “freak offs” — what the indictment describes as “elaborate and produced” sex performances — with victims and sex workers, notes instances of physical and sexual abuse and illuminates what law enforcement found in the March raids of his homes.
