Two people died and eight were injured in a stampede after a concert by rapper GloRilla in Rochester, New York.
Authorities say the crush may have been triggered when audience members mistakenly thought they heard gunshots.
However, Rochester police lieutenant Nicholas Adams told ABC News there was “no evidence to support a shooting had occurred”.
GloRilla, who had finished performing before the incident, said she was “devastated and heartbroken”.
The Memphis musician, whose song F.N.F. (Let’s Go) was nominated for best rap performance at last month’s Grammy Awards, said she did not hear about the stampede until she left the venue.
“My fans mean the world to me,” she wrote on social media. “Praying for their families and for a speedy recovery of everyone affected.”
