U.S. federal prosecutors have amended an indictment of Sean ‘Diddy’ Combs, accusing him of “forced labor.”

Combs is facing a federal trial in May on charges of racketeering and sex-trafficking, as well as transportation for prostitution. He has pleaded not guilty.

Combs’ lawyers claim that he forced his workers to work long shifts and threatened those who didn’t help his alleged drug trafficking ring.

Though no official charges have been added, the indictment details the new allegations, including that employees were forced to “work long hours without much sleep.”

Marc Agnifilo said that Combs was looking forward to the day when he would be able to prove to the court that he never forced someone to perform sexual acts without their consent.

Combs is facing several allegations of sexual abuse. Some of these allegations are said to date back several decades.

Combs is being held in the Brooklyn Metropolitan Detention Center, where Luigi Mangione, the accused killer of UnitedHealthcare CEO Brian Thompson, is also held.
