Sean "Diddy" Combs has been breaking prison rules by contacting potential witnesses in his upcoming sex trafficking trial, prosecutors have alleged.

The music mogul is accused of making "relentless efforts" to "corruptly influence witness testimony", by using other inmates' telephone accounts and using three-way calls to speak to people who are not on his approved contacts list.

Prosecutors said a review of recorded calls also found that Mr Combs instructed his family to contact potential witnesses in his case, they said in a court filing.

Mr Combs, 55, is currently in custody in Manhattan. He has pleaded not guilty to all of the charges against him and strenuously denied any wrongdoing.

Best known for 1990s hits such as I'll Be Missing You and Mo' Money, Mo' Problems, the musician has been denied bail since his arrest, with multiple judges citing a risk that he might tamper with witnesses.

His lawyers made a renewed bid for bail last week, proposing a $50m (£39.6m) package that would see Mr Combs be monitored around the clock by security personnel, while under house arrest.

Lawyer Alexandra Shapiro argued the musician couldn't prepare for trial from behind bars because of the "incredibly voluminous" amount of material to review, especially without a laptop computer.

She also said his preparation has been hampered by conditions at the jail, including frequent lockdowns and officers taking away the pens he uses to take notes.

Detention is stripping Mr Combs of "any real opportunity" to be ready for trial, violating his rights under the US Constitution, Shapiro said.

In response, prosecutors argued that the request for bail should be denied, alleging that Mr Combs "poses serious risks of danger and obstruction of these proceedings".

In court documents, they accused the star of orchestrating social media posts in order to "influence a potential jury pool" at his trial.

Amongst those efforts, they cited an Instagram statement posted by a woman known only as "witness two", countering allegations made by singer Dawn Richard in a civil lawsuit against Mr Combs.

Prosecutors alleged that her statement was drafted with Mr Combs during "multiple texts" and "multiple calls" from prison.

They further alleged there was a "strong inference" that Mr Combs "paid witness two after she posted her statement".

A video posted by the star's seven children on 5 November was also cited as evidence of a "public relations strategy to influence this case".

The video, which was reported by multiple media outlets, showed the family wishing Mr Combs a happy birthday during a prison phone call.

"The defendant then monitored the analytics - i.e. audience engagement - and explicitly discussed with his family how to ensure that the video had his desired effect on potential jury members in this case," prosecutors said.

Mr Combs was also accused of using the phone accounts of at least eight other inmates to make calls, which is against prison regulations; and of "directing others" to orchestrate payment for this access.

Prosecutors characterised Mr Combs as running a "relentless" scheme to "contact potential witnesses, including victims of his abuse who could provide powerful testimony against him".

'Uncanny ability'

Urging the judge to deny Mr Combs' request for bail, the prosecutors wrote that "no set of conditions" could eliminate the potential risks to the trial.

"The defendant has demonstrated an uncanny ability to get others to do his bidding - employees, family members, and [prison] inmates alike," they claimed.

"There is no reason to believe that private security personnel would be immune."

Prosecutors also rejected criticism of the conditions at the Metropolitan Detention Center in Brooklyn, citing an interview from the star's lawyer Marc Agnifilo, who said "food’s probably the roughest part" of Mr Combs' adjustment to life behind bars.

The musician's lawyers have yet to react to the court motion. The BBC has contacted his legal team for a response.

Mr Combs' legal troubles began last November, when his ex-partner Cassandra "Cassie" Ventura filed a civil lawsuit, alleging incidents of rape and physical assault between 2007 and 2018.

Although the case was quickly settled out of court, it led to a flurry of similar accusations and an investigation by the US Government.

The star's properties were raided by federal agents in March, and he was arrested in New York in September.

Mr Combs was charged with three counts of sex trafficking and racketeering, in a federal indictment that described allegations of drug-fuelled, days-long sexual performances dubbed as "Freak Offs".

The musician is simultaneously facing more than two dozen civil cases by men and women accusing him of sexual assault, rape and sexual exploitation.

The star has vehemently denied all of the charges against him, and the claims in the civil suits, arguing that the sexual encounters at the heart of his criminal case were all consensual.
