Former rap music mogul Marion "Suge" Knight has been released from hospital and taken back in to police custody.
Mr Knight, 49, complained of chest pains on Tuesday about an hour after pleading not guilty to murder and attempted murder.
Los Angeles County Sheriff's Department Deputy Kelvin Moody said Mr Knight was released and taken into custody around 0900 local time on Wednesday.
He is accused of intentionally running down and killing a friend on 29 Jan.
Mr Knight, who founded Death Row Records, which featured Snoop Dogg, Dr Dre and Tupac Shakur as its top artists, faces a total of four charges under his real name Marion Hugh Knight and faces life in prison if convicted.
It is alleged a truck Mr Knight was driving hit and killed his friend Terry Carter, 55, in the incident in the suburb of Compton last week.
Another man, Cle "Bone" Sloan, 51, was injured.
The former record label boss's lawyer said his client was trying to escape an attack at the time.
On Monday, a court commissioner revoked the $2m (£1.3m) bail after police said the defendant had a violent past and could intimidate witnesses.
Mr Knight founded Death Row Records in the 1990s but later declared bankruptcy and the company was sold at auction.
The music producer has previously been convicted of armed robbery and assault with a gun.
