Sean “Diddy” Combs’ arrival at FCI Allenwood Low places the disgraced music mogul inside a Pennsylvania federal prison with a troubling history of allegations involving inmate treatment and coordinated violence. Combs, 56, was transferred after spending the past year at FCI Fort Dix in New Jersey.

The Federal Bureau of Prisons confirmed the transfer to Page Six on Friday. The agency did not disclose the circumstances behind moving Combs from the New Jersey facility to Allenwood Low.

The Pennsylvania prison was previously accused of subjecting an inmate to “inhumane” treatment. It also housed prisoners later indicted in connection with an alleged coordinated assault involving makeshift weapons.

Rapper Sean "Diddy" Combs is on the move, according to multiple sources familiar with the situation.

One of the most disturbing allegations emerged in a 2017 lawsuit filed by former inmate Anthony Mammana. He accused a prison lieutenant of retaliating against him by confining him for four days inside a freezing room known as the “Yellow Room.”

Mammana claimed officials stripped him of his normal clothing and forced him to wear thin, transparent garments. He said he was denied blankets, sheets, and a pillow during the confinement.

According to Mammana, bright lights remained on around the clock and deprived him of sleep. He also alleged that guards mocked him while denying him toilet paper, soap and towels.

A court agreed that Mammana’s treatment was inhumane. However, a legal technicality prevented him from pursuing damages over what happened inside the facility.

Allenwood Low later became the setting for a separate criminal case involving alleged violence among prisoners. In September 2025, federal prosecutors announced that 17 inmates had been indicted over an alleged gang-related conspiracy to assault other prisoners in June 2023.

Prosecutors alleged that the defendants conspired to attack inmates with dangerous weapons. Those alleged weapons included locks and other heavy objects attached to strings, belts and socks.

Authorities said the coordinated assault grew out of a turf dispute inside the prison. The alleged purpose was to forcibly seize control of the housing unit’s television and telephone areas.

Several defendants also faced charges of possessing prohibited weapons inside the institution. The prosecution was brought under a Department of Justice initiative targeting transnational criminal organizations.

Representatives for the Bureau of Prisons did not respond to a request for comment concerning Allenwood Low. The agency also declined to discuss why Combs was transferred.

The move came days after Combs suffered a head injury while incarcerated at Fort Dix. TMZ subsequently reported that he had been involved in a fight with fellow inmate Christopher “Dudus” Coke, a convicted Jamaican drug lord, but Combs’ family denied the report.

Combs’ relocation also followed reports that his time at Fort Dix had been surprisingly comfortable. NBC News reported last month that four inmates alleged he had access to massages, premium alcohol and a cellphone while incarcerated there.

Those inmates further claimed that other prisoners cooked for Combs and cleaned his living space. His representative pushed back on the allegations, telling Page Six that Combs was serving his sentence in accordance with prison rules while pursuing an appeal.

The Bad Boy Records founder was sentenced to 50 months in federal prison in October 2025. His sentence followed convictions on two counts of transportation to engage in prostitution.

Combs was acquitted of the more serious charges of sex trafficking and racketeering conspiracy following his federal trial in New York. He is appealing both his conviction and sentence, and his projected release date is currently March 2, 2028.
