The mainland China-based creditor of Hip Hing Loong Stage Engineering Company on Friday filed a case with the city’s High Court for the firm to be liquidated, with a hearing slated for April 23.

Dancers Mo Li Kai-yin and Chang Tsz-fun were hit by a giant video screen weighing 500kg (1,102lbs) that fell onto the stage during the fourth of 12 concerts at the Hong Kong Coliseum in Hung Hom on July 28 as a result of a snapped cable.

Li was severely injured, paralysed from neck below and has been in rehabilitation.

Another dancer, Zisac Law Tak-chi, fell two to three metres (6.6 to 9.8 feet) during a rehearsal for the first concert on July 25 after an elevating platform failed to ascend to the stage as expected. He suffered chest and knee injuries, and sprained his neck.
