At least 42 people were injured on Friday night after a fence collapsed as fans spilled over the ledge during rapper Snoop Dogg's concert in New Jersey, authorities said.
The incident occurred when Snoop Dogg and Wiz Khalifa were performing at an amphitheatre in Camden, CNN reported.
Most of the injuries were minor, organisers said.
The concert was stopped after the incident, philly.com reported.
Several videos show dozens of people tumbling on top of each other. Snoop and Wiz were ushered off the stage as security moved in to help the fans.
