Sean “Diddy” Combs was accused of illegally using the telephone privileges of other inmates at the Metropolitan Detention Center in Brooklyn to secretly communicate with witnesses and evade surveillance, according to federal prosecutors.

In a newly unsealed filing, prosecutors allege the Hip-Hop mogul used phone systems designed for other inmates to make unmonitored contacts, an alleged tactic to evade federal regulations.

The announcement comes as prosecutors push to deny Diddy’s bond.

They argue that his “flagrant” failure to comply with Bureau of Prisons (BOP) rules makes him unreliable in determining that he can comply with court-ordered conditions if he is granted release.

“The defendant is well aware of BOP policies, but has consistently chosen to ignore them, jeopardizing the integrity of institutional procedures designed to protect public safety and investigations,” prosecutors wrote in their recent filing.

Diddy is currently being held at the Brooklyn facility as he faces a slew of federal charges ranging from racketeering, sex trafficking and orchestrating interstate prostitution.

The racketeering charge alleges that Diddy ran a criminal organization called Combs Enterprise that operated a vast illegal network for over a decade.

From 2008 to 2024, indictment alleges that Diddy coerced women into engaging in degrading acts, often through violence and manipulation.

Prosecutors say he hosted extended sex shows, dubbed “Freak Offs,” during which he threatened, abused and exploited women — sometimes recording the acts to maintain control over his victims.

In addition to the racketeering conspiracy, Diddy faces charges of sex trafficking and facilitating the interstate transportation of persons for prostitution.

Prosecutors allege that Diddy used force, fear and coercive tactics to get the women to comply with his demands while the “Combs Enterprise” carried out multiple acts of violence, including kidnappings and arson.

But prosecutors say his illegal behavior didn’t stop when he went into custody.

They say that while incarcerated, he used other inmates’ PAC numbers — the personal access codes needed for calls — to make unauthorized phone calls.

In their review, they examined dozens of such calls, revealing extensive efforts by Combs to circumvent BOP regulations.

Diddy allegedly paid fellow inmates — either through electronic money transfers using payment apps or by depositing funds into their escrow accounts — in exchange for their PAC numbers.

The PAC sharing process opens up a vulnerability in the detention center’s monitoring system, allowing inmates like Diddy to hide their communications from law enforcement.

In addition to the phone abuse, Diddy used a third-party messaging app, ContactMeASAP, to send hundreds of encrypted messages.

Prosecutors say he maintained his anonymity by using email addresses linked to others, including one of his sons, to exchange those communications.

Federal prosecutors point out that Diddy began implementing these secret communication methods shortly after arriving at the facility, signaling, they say, a pattern of disregard for the rule of law.

Such behaviour, they argue, “speaks volumes” about his inability to comply with legal restrictions if granted release.

Diddy’s fifth hearing is scheduled for November 22.
