MOUNTAIN VIEW, Calif. (TheBlaze/AP) — A 38-year-old man died Saturday after being shot multiple times backstage during a rap concert, authorities said.

The shooting occurred at Shoreline Amphitheatre where Pittsburgh rapper Wiz Khalifa, Atlanta hip hop artist Jeezy and others had finished performing Friday night. The victim, whose name was not immediately released, died at a hospital.

Police rushed to the outdoor venue after receiving multiple calls that shots had been fired but no arrests have been made. Officers were still looking for a male suspect believed to be in his 20s and armed with a handgun — described as a black pistol with a large magazine, KTVU-TV reported, citing Mountain View police.

Investigators asked concertgoers for photos or videos that might provide clues.

Authorities don’t yet know how a gun made it into the amphitheater, where patrons undergo security screening, Mountain View police spokeswoman Shino Tanaka told the station.

Wiz Khalifa was scheduled to continue his Under the Influence of Music Tour at Sleep Train Amphitheater in Chula Vista, California, on Saturday night, but the show was canceled, according to a recorded message by the venue that did not give a reason.

He has another concert scheduled Sunday in Irvine, California.

The rapper has been in the news for offstage incidents of late. The BBC reported that a warrant was issued for his arrest in earlier this month after he failed to appear at a scheduled hearing in Texas over a 2013 misdemeanor arrest for possession of marijuana. E! News noted that Khalifa opted for an appearance on ”The Tonight Show Starring Jimmy Fallon” instead.
