Kodak Black was the victim of an alleged prison beating.

On Friday night, the rapper–whose legal name is Bill Kapri–says he was “badly beaten” by seven guards at USP Big Sandy, a high-security federal prison in Kentucky. According to his Instagram post, the guards repeatedly struck him in the head with a metal object while handcuffed. One of the officers reportedly “flicked his genitals” and told him, “You’re not so gangster now, you’re gonna need bigger balls to survive.”

As a result of the incident, Kodak’s legal counsel wants the Justice Department and the FBI to conduct a full investigation. His lawyer, Bradford Cohen, has requested that Big Sandy preserve all video evidence. He claims there are recordings of witnesses vouching for what happened to Kodak.

“A 22 year old man serving approx 2 years more for a non violent crim is in a max pen. 1100 miles from his family and lawyers. This is true injustice,” said Cohen. “Not to mention when he was under the influence of an unknown substance during the incident in Miami 2 weeks before his sentencing on the paperwork case.”

While at FCI Miami in October, Kodak allegedly grabbed a corrections officer’s testicles before he was sprayed with mace and had to be restrained by prison guards. The staff member was taken to a hospital to undergo surgery. An FBI agent testified that witnesses said Kodak appeared to be under the influence of an unknown substance when the fight broke out.

In January, Kodak complained that prison officials were conspiring against him and that he had to endure inhumane conditions. “They are strategically killing me slowly in here. I have been humiliated over and over again,” he wrote on Instagram. “I am highly disappointed in the way they have treated not only me, but all the other inmates in this facility.”

The “Tunnel Vision” rapper is serving 46 months on weapons charges and is scheduled to be released on Aug. 14, 2022.

Last week, Kodak asked for a meeting with Donald Trump to discuss a “brilliant idea” he had. “This ain’t got nothing to do with my wrongful conviction,” he told the President. “If it’s not worth anything you can kill me!”
