Two people were rushed to hospital after a horrific incident at a concert saw them crushed by a huge screen which fell from the roof.
A back-up dancer for the Cantopop boy band Mirror is in intensive care while another is being treated following the gig in Hong Kong.
Five people were injured when the panel -- measuring about four square meters -- fell onto the stage during the show at the Hong Kong Coliseum near Victoria Harbour.
Video of the moment the screen crashed onto the dancers went viral on social media
Hong Kong's Chief Executive John Lee has called for an investigation.
"I have contacted the Secretary for Culture, Sports and Tourism, and instructed the Leisure and Cultural Services Department, together with relevant departments, to comprehensively investigate the incident and review the safety requirements of similar performance activities in order to protect the safety of performers, working staff and members of the public," Lee told CNN.
Kevin Yeung, Hong Kong's culture secretary, said Friday that the panel had fallen because one of the cables holding it was loose.
"From initial observation, a wire fractured and led to the fall of the screen and caused the dancers to be injured," Yeung told reporters Friday. Hong Kong's Labour Department Secretary Chris Sun said Friday he will not rule out legal action against those responsible.
In a statement on Facebook, the organizer of the concert, Makerville, apologized for causing "unease to viewers or others affected" and said that people who attended Thursday's concert would be eligible for a refund.
