LOS ANGELES (AP) — Former rap mogul Marion “Suge” Knight remains in a hospital where he was taken for chest pains after he entered a not guilty plea to a murder charge.

Los Angeles County sheriff’s Deputy Guillermina Saldana said Wednesday the agency cannot provide any further details on the 49-year-old Knight, who is accused of intentionally running down and killing a friend on Thursday. Another man was injured. Knight complained of chest pains on Tuesday about an hour after he pleaded not guilty to murder, attempted murder and hit-and-run charges.

Knight’s attorney David Kenner has not returned phone messages seeking an update on his client’s health.

Knight founded Death Row Records, which once featured Snoop Dogg, Dr. Dre and Tupac Shakur as its top artists.
