According to the news report, the large steel grid, on which a substantial amount of technical equipment was rigged, collapsed in the early afternoon during set-up. It also mentions that whilst most people escaped unhurt, three sustained minor injuries. The truss was apparently attached to the Boardwalk's false ceiling which was installed in the venue as part of a recent $90 million upgrade. An investigation is now underway.
