A shooting at Musikfest in Bethlehem, Pennsylvania on Saturday resulted in a chaotic scene that saw several attendees get trampled. 

As The Morning Call reports, law enforcement, including FBI agents, arrived at the festival at around 11:00 p.m. local time after the shooting caused what witnesses described as a stampede. “I saw a lot of people falling and get stepped on,” one person wrote on Facebook. “I helped a young man who’s hands were bleeding pretty bad and couldn’t catch his breath (he’s ok).”

Police described the shooting as an isolated incident, and Bethlehem Police Chief Michelle Kott said the festival was shut down as a safety precaution. “Law enforcement is on site and in control of the situation,” Kott said. “There is no known continuing threat to the public.”

Musikfest is scheduled to resume on Sunday, August 14th. This year’s lineup included performances from the likes of Willie Nelson, Counting Crows, Disturbed, and Ziggy Marley, among others.

The Musikfest shooting is one of a mounting number of events struck by violence. Seven people were killed and dozens more were injured after a gunman opened fire at a Highland Park, Illinois Fourth of July parade, and while no one was seriously injured, the air of fun and catharsis was dampened at a recent Dua Lipa concert when unauthorized fireworks went off in the crowd.
