Nineteen others were injured when the temporary scaffolding outside Cape Town's Green Point stadium collapsed shortly before the evening concert, the South African Press Association said on Thursday.
Twelve of those required hospital treatment. "One person passed away last night as a result of injuries. It was a female individual. She passed away after she was taken to hospital," city spokeswoman Kylie Hatton said.
Linkin Park said that they had only learnt about the death after the concert, which went ahead as planned despite the rough weather. "We wish to express our deep sadness and concern for those injured and our heartfelt condolences to the family of the fan who died as a result of her injuries," the band said in a statement on its website.
