A big video panel collapsed onto the stage during a performance by the Hong Kong boyband Mirror, hurting at least two dancers, one of whom was gravely hurt. As a result, the group was temporarily banned from performing while an inquiry was underway.

Social media was flooded with videos of the screen toppling, and Hong Kong media reported that three audience members reportedly suffered injuries.

“I am shocked,” said Hong Kong Chief Executive John Lee. “I express sympathy to those who were injured and hope that they would recover soon.”

The government would investigate and review safety procedures to protect performers, staff and the public, he said.

None of the 12 members of Mirror were hurt in the accident at Hong Kong’s Coliseum, next to Victoria Harbour.

The city government had ordered the band, which was putting on a run of 12 shows at the venue, to postpone its upcoming performances.

Culture Secretary Kevin Yeung said shows at the venue were suspended until its stage structure was deemed safe.

“From initial observation, a wire fractured and led to the fall of the screen and caused the dancers to be injured,” Yeung told a media briefing on Friday.

The hugely popular cantopop group was formed in 2018 through a reality television show.

More than 13,000 Mirror fans signed an online petition asking the concert organiser to fix the problems and ensure the safety of all.

Concert organiser MakerVille, which is owned by Hong Kong tycoon Richard Li’s PCCW Media Group, said it was thoroughly investigating the accident.

“We are deeply sorry that the incident caused unease to viewers or others affected,” it said.
