NEWPORT BEACH, Calif. (AP) — California prosecutors say platinum-selling rapper Young Jeezy has pleaded not guilty to possessing an illegal assault weapon during an investigation into a fatal shooting at a rap concert.

A spokeswoman for the Orange County district attorney says the rapper, whose real name is Jay Wayne Jenkins, entered his plea to the felony charge Tuesday. The spokeswoman, Farrah Emami, says the rapper and five others were arrested Sunday at the Verizon Amphitheatre in Irvine. The other five also pleaded not guilty to possessing an AK-47 assault rifle.

Jeezy remains jailed on $1 million bail. He’s due back in court Sept. 5.

Authorities are still investigating who fatally shot a man backstage Friday at a concert Jeezy co-headlined with Wiz Khalifa at Shoreline Amphitheatre in Mountain View.

Authorities say none of those charged are being called suspects in the shooting.
