Officials now say that a failed clamp was behind the accident that injured several acrobats and performers at a Ringling Bros. and Barnum & Bailey Circus performance in Providence, Rhode Island.
Eight acrobats were hanging by their hair from a platform that suddenly fell from the ceiling. Some performers on the ground were also injured.
Two of the injured were still in critical condition, as of this morning. Three are listed in serious condition and three others in good condition. Local authorities and officials from the federal Occupational Safety and Health Administration are investigating.
Tonight's final performance in Providence has been canceled.
