TORONTO (Reuters) - A concert by the British rock band Radiohead was canceled after a portion of the stage collapsed during sound checks before the show on Saturday, killing one person and injuring several others, the Canadian Broadcasting Corporation reported.
Police and fire officials reached by Reuters did not immediately confirm the death.
The CBC said at least three people were seriously hurt in the accident, which occurred at about 4 p.m. local time at Downsview Park, about 5 miles north of downtown Toronto.
Representatives for the concert's promotion company, Live Nation, were not immediately available for comment. Downview Park officials had no comment on the incident except to confirm that the Radiohead concert had been canceled as a result.
Toronto police spokesman Sergeant Tim Burrows said an unknown number of people near the stage at the time were injured and taken to the hospital.
Rehearsals and sound checks were being conducted at the venue when the collapse occurred, but the headline band Radiohead was not on stage at the time, Burrows said, adding that investigators were still unsure what caused the mishap.
Pictures of the scene posted on social media sites showed a large section of metal scaffolding over and around the stage that had collapsed in the middle of the concert platform.
There were about 20 people in the direct vicinity of the stage when it gave way, he said.
"I'm not sure where it stands right now, but Toronto Fire Services is securing the scene," he said.
Radiohead, an alternative rock group led by singer Thom Yorke and famed for such hits as "Creep" and "Paranoid Android," is on an international tour this summer.
Their 1997 album "OK Computer" established the band as one of the top musical acts of the decade. The group made waves with its 2007 collection "In Rainbows," which the band ambitiously released first as a digital download while allowing customers to set their own price for it.
