DENVER (AP) - A storied outdoor amphitheater at the front door of the Rocky Mountains became a scene of violence when a man with a rifle fired at an SUV carrying rapper ScHoolboy Q after a concert, investigators said.
The rapper was not hurt but three other people in the vehicle sustained non-life threatening injuries. No arrests have been made in the Thursday night shooting.
Police were trying to determine a motive for the attack in a parking lot at Red Rocks, where the Beatles and Grateful Dead have performed and U2 filmed "Under a Blood Red Sky."
Investigators said they did not know if ScHoolboy Q was targeted.
"We have a lot to learn," said Jacki Kelley, a spokeswoman for the Jefferson County Sheriff's Department.
ScHoolboy Q, whose birth name is Quincy Matthew Hanley, is from Los Angeles. His most recent album, "Oxymoron," debuted at No. 1 earlier this year and reflects his life as a father and former gang member.
He and Kendrick Lamar, who was nominated for seven Grammys this year, are members of Black Hippy.
ScHoolboy Q said on Twitter Friday that he was OK.
"im str8...... dont trip," he wrote.
In March, when ScHoolboy Q played at a sold-out show in Denver, someone in the crowd threw an object at the performer, who jumped off the stage to confront the person, The Denver Post reported. Security staff separated them.
Ray Alba, a representative for ScHoolboy Q, didn't immediately return a phone call seeking comment.
The rapper and at least four other people were in the white SUV that was fired on at the venue in the foothills west of Denver, authorities said.
They drove themselves to a Denver intersection about 15 miles away, apparently in search of a hospital, before being stopped by Denver police and taken for medical attention, Kelley said.
ScHoolboy Q and another uninjured person were briefly handcuffed while police assessed the situation, but no one in the vehicle was arrested. Kelley said ScHoolboy Q was not a suspect in the shooting.
Nas and Flying Lotus also performed at the concert that benefited three groups, including the Gang Rescue and Support Project of Denver.
Promoters said the gang rescue group got 5 percent of the profits. Two other groups also got 5 percent each: Preserve the Rocks, which helps preserve the Red Rocks venue, and Helping Our People Excel, a Denver-area charity with a food pantry and other services.
About 4,500 people attended the concert at the amphitheater, which seats as many as 9,525 people.
The amphitheater and surrounding park are popular with joggers and sightseers.
