Suge Knight has reportedly been told he might have a brain tumour.

The controversial music mogul, who was charged with murder and attempted murder following a fatal hit-and-run earlier this year, suffers from numbness on one entire side of his body and doctors have reportedly told him he might have a brain tumor.

The 50-year-old record producer - who's known for his association with rappers Tupac Shakur and Dr. Dre, among others - has complained about the state of his cell and is looking to be moved to somewhere better, arguing its condition is taking a mental and physical toll on him, TMZ reports.

What's more, Suge claims his prison cell toilet flushes every 20 minutes on its own and that the bed in his current cell isn't big enough to rest his 6'2'' frame.

Suge's lawyers have argued he needs full access to a competent medical facility and a more comfortable cell in order to enjoy a good night's sleep.

In April, Suge pleaded not guilty to allegations he murdered businessman Terry Carter and attempted to murder Cle 'Bone' Sloan by running them over with his car following an altercation in January.
