Three people were arrested on disorderly conduct charges, police said. Authorities also shut down the audition, saying it wasn't properly organized.
Four injured people declined treatment, while two others were taken to a hospital, the fire department said. Their conditions weren't immediately available.
The phone rang unanswered at the hotel, and representatives for The CW Network, which airs the reality show, didn't immediately return calls.
The model competition is hosted by supermodel Tyra Banks, who also serves as its executive producer. The current season began March 4.
Her agent and publicist didn't immediately return telephone calls.
Banks has said she created the show to counter stereotypes about beauty, and Saturday's auditions were open only to women no taller than 5-foot-7, which is shorter than the industry's conventions.
Tryouts also were being held this month around the country, including in Dallas, Chicago and Los Angeles.
