Kodak Black is speaking out from behind bars.

The rapper, also known as Bill K. Kapri, is opening up about his “cruel and unethical” experience in prison, where he is serving a 46-month sentence on weapons charges. In a note posted to Instagram on Thursday, he claims there is a “big conspiracy” against him by two of the officials inside Miami’s Federal Detention Center, who are “strategically killing me slowly.”

According to Kodak, Lieutenant F. Arroyo and Santiago Torres have been “very vindictive” towards him and are falsifying incident reports, taking away visitation rights, and interfering with his mail.

“There is a big conspiracy going on in this building on Me. Santiago Torres is using her position wrongfully in Miami FDC and is abusing her authority,” writes Kodak. “She has been writing falsified incident reports on me, to take phone privileges that I get once a week while in solitary.”

He claims Torres is “abusing her authority” and threatened to take his girlfriend off his visitation list. “For no other reason but to add insult to my distress,” explains Kodak. “Not being able to see my significant other while locked away in this hell hole.”

He also claims that he was denied a visit with his mother two days before Christmas and that his mail is taking a month to receive and outgoing mail is being tampered with. “My family hasn’t received none of my letters for the holidays. Which is borderline cruel and unethical,” he adds.

Additionally, Kodak says he was given an empty tray for breakfast on New Year’s Eve. “I brought it to their attention, but nothing was done for me. Since the camera shows them entering a tray through my flap, but meanwhile there is nothing in my tray when i. opened it.”

Kodak complains that the treatment towards him and other inmates is inhumane. “They are strategically killing me slowly in here. I have been humiliated over and over again,” he says. “I am highly disappointed in the way they have treated not only me, but all the other inmates in this facility. With their self serving agenda they will always side with their fellow officers whether right or wrong.”

He also details his fellow inmate Pete’s experience that ended in death. “Pete’s health condition reached a very advanced Stage while he was in excruciating pain!” he says. “So, Pete requested medical attention (like myself) which was denied ( like myself) because he felt like he was dying ( like myself ).”

Pete eventually took his own life. “It’s sad because everyone was aware of his health issues and one C O could have found it in the kindness of the heart to do their jobs and simply call medical, his family wouldn’t be mourning his loss as of now,” adds Kodak, who offered his condolences and money to Pete’s family. “I tried to do this sooner but they are not sending my mail out.”

Kodak remains in federal custody after being sentenced to 46 months on weapons charges. In November, he was hit with two additional gun charges for possession of a firearm by a convicted felon and faces up to 30 years in prison on each count.
