Sean “Diddy” Combs has tried to reach out to prospective witnesses and influence public opinion from jail in a bid to affect potential jurors for his upcoming sex-trafficking trial, prosecutors claimed in a court filing urging a judge to reject his latest bail request.

The government accusations were made late Friday in a Manhattan federal court filing that opposes the music mogul’s latest $50m bail proposal. A bail hearing is scheduled for next week.

Prosecutors wrote that a review of recorded jail calls made by Combs shows he has asked family members to reach out to potential victims and witnesses and has urged them to create “narratives” to influence the jury pool. They say he also has encouraged marketing strategies to sway public opinion.

“The defendant has shown repeatedly – even while in custody – that he will flagrantly and repeatedly flout rules in order to improperly impact the outcome of his case. The defendant has shown, in other words, that he cannot be trusted to abide by rules or conditions,” prosecutors wrote in a submission that contained redactions.

Prosecutors wrote that it could be inferred from his behavior that Combs wants to blackmail victims and witnesses into silence or into providing testimony helpful to his defense.

Lawyers for Combs did not immediately respond to requests for comment.

Prosecutors said Combs, 55, began breaking rules almost as soon as he was detained at the Metropolitan detention center in Brooklyn after his September arrest.

He has pleaded not guilty to charges that he coerced and abused women for years with the aid of a network of associates and employees, while silencing victims through blackmail and violence, including kidnapping, arson and physical beatings.

Two judges have concluded he is a danger to the community and a risk to flee.

His lawyers recently made a third request for bail after the rejection of two previous attempts, including a $50m bail proposal.

In the request, they cited changed circumstances, including new evidence, which they said made it sensible to release Combs so he can better prepare for his 5 May trial.

But prosecutors said defense lawyers created their latest bail proposal using evidence prosecutors had turned over to them and that the material had already been known to defense lawyers when they made previous bail applications.

In their submission, prosecutors said Combs’ behavior in jail shows he must remain locked up.

For instance, they said, Combs has enlisted family members to plan and carry out a social media campaign around his birthday “with the intention of influencing the potential jury in this criminal proceeding”.

Combs encouraged his children to post a video to their social media accounts showing them gathered to celebrate his birthday, they said.

Afterward, he monitored the analytics, including audience engagement, from the jail and “explicitly discussed with his family how to ensure that the video had his desired effect on potential jury members in this case”, they said.

The government also alleged Combs during other calls made clear his intention to anonymously publish information that he thought would help his defense against the charges.

“The defendant’s efforts to obstruct the integrity of this proceeding also includes relentless efforts to contact potential witnesses, including victims of his abuse who could provide powerful testimony against him,” prosecutors wrote.
