A platform collapsed during an aerial hair-hanging stunt at a circus performance in the US, sending eight entertainers plummeting to the ground.
Nine performers were seriously injured in the fall, including a dancer below.
The accident occurred during the Ringling Brothers and Barnum and Bailey Circus' Legends show at the Dunkin' Donuts Centre in Providence, Rhode Island.
Stephen Payne, a spokesman for Feld Entertainment, the parent company of Ringling Bros, said the accident happened during an act when eight female performers hang "like a human chandelier" using their hair.
He said the metal-frame apparatus from which the performers were hanging came free from the metal truss it was connected to. The eight women fell up to 40 feet, landing on a dancer on the ground.
Providence public safety commissioner Steven Pare said officials and inspectors have not yet determined what caused the accident. He said none of the injuries appears to be life-threatening.
The hair-hanging stunt is described on the circus's website as a "larger-than-life act" featuring eight female performers.
"These 'hairialists' perform a combination of choreography and cut-ups including spinning, hanging from hoops, and rolling down wrapped silks, all while being suspended 35 feet in the air by their hair alone," the description says. "In this hair-raising act, audiences will even see the weight of three girls held aloft by the locks of only one of these tangled beauties."
Sydney Bragg, 14, said the collapse happened about 90 minutes into the show. She said the platform began to fall as it neared the rafters of the arena. At first, she said, she thought it was part of the act.
"It just went crashing down," Sydney said. "Everyone was freaking out. We heard this huge clatter and then we just heard the girls scream."
She said spotlights were on the performers at the time, but all the lights went out after the fall.
Rosa Viveiros said the act was covered by a curtain. Shortly after the curtain was pulled away, she said, the performers fell on top of at least one other performer, a man who stood up with his face bloodied.
"We thought it was part of the circus," said Rosa Viveiros's husband, Joe.
The Dunkin' Donuts Centre said two shows scheduled for later today and two others for tomorrow are on hold.
Roman Garcia, general manager of the Legends show, asked people to pray for the performers.
"Everybody's doing fine, everybody's at the hospital, everybody's conscious, everybody's doing pretty well," he said at the Dunkin' Donuts Centre less than two hours after the accident.
Rhode Island Hospital in Providence admitted 11 patients with varying injuries, including one in a critical condition, spokeswoman Jill Reuter said.
