One person was killed when a stage collapsed just minutes before audiences were set to begin streaming in to watch a sold-out show in Toronto by alternative rock band Radiohead.

The stage at Downsview Park collapsed around 4 p.m. Saturday afternoon, leading to one man pronounced dead at the scene, and another to suffer serious injuries according to a CNN report. Two others with minor injuries were also sent to Toronto's Sunnybrook Hospital, and have since been released.

The victims were setting up a stage in the park when a "scaffolding-type structure collapsed" about 40 to 60 feet above the main stage area, Toronto fire Capt. Mike Strapko said. Winds and bad weather are not speculated to be the cause.
