Rapper Young Jeezy was arrested Sunday night on weapons charges in an investigation following a fatal shooting at a Wiz Khalifa concert.

Jeezy, or Jay Jenkins, was arrested along with five others at Verizon Wireless Amphitheatre in Irvine, California after his tour bus was searched and an assault rifle was discovered.

The investigation follows a homicide Friday evening, in which a 38-year-old man was shot backstage at a Wiz Khalifa concert at Shoreline Amphitheater in Mountain View. 

Jeezy is being held at the Orange County Police Department, where bail is set at $1 million.
