Former Death Row Records owner Marion “Suge” Knight has reportedly filed legal documents over the treatment he has received behind bars in a publicized fatal hit-and-run case.

According to reports, Suge is arguing to gain back his basic human rights.

Suge filed legal docs, obtained by TMZ, in which he says the L.A. County Sheriff’s detective in charge of his murder case got a judge to shut down his ability to communicate with the outside world for an indefinite period of time. Suge says he’s now sitting in isolation, unable to even make a phone call. The docs don’t say why the Sheriff’s Dept. wants Suge radio silent … it could have something to do with alleged witness intimidation. We’ve reached out to the Dept. but they’re not talking. (TMZ)

Earlier this month, details about Suge losing multiple privileges surfaced online.

Former rap mogul Marion “Suge” Knight’s access to visitors and phone calls have been completely cut off at the request of sheriff’s investigators, court records shows. Court records show Los Angeles Superior Court Judge William C. Ryan on Friday cut Knight’s access to phone calls and non-attorney visitors. The order was issued at the request of a sheriff’s detective investigating Knight’s murder case, in which he is charged with running over two men, killing one, outside a Compton burger stand in January 2015.

Knight fired attorney Tom Mesereau following a disagreement last month.

Our sources say Suge and Mesereau had a bitter disagreement over confidential information. We’re told Suge claims the info made its way to authorities and he became enraged. Here’s what’s odd … the judge allowed our camera in the courtroom but then pulled the plug a minute after Suge’s case was called and then cleared the entire courtroom so no member of the media or public could hear the reason for the lawyer/client split.

Last year, Mesereau said his client may have a brain tumor.

Even more serious — Mesereau says Suge suffers from numbness on one entire side of his body and doctors have told him he might have a brain tumor. As such, he wants a place that has full access to a competent medical facility. He’s currently locked up on $10 million bail. (TMZ)
