Police continued to interview witnesses including lighting and sound technicians, dancers, and a member of security at the headquarters of the Kowloon West regional crime unit in Kowloon City on Monday.

Sources said earlier that the force had talked to most of the dancers involved in the accident, with a third of them already given their statements.

A force insider said police were still arranging interviews with Mirror band members Anson Lo Hon-ting and Edan Lui Cheuk-on, who were onstage when the screen fell.

Lo Ting-fai, the chief executive of MakerVille, one of the concert organizers, and Francis Lam Ho-yuen, a producer responsible for the group’s We Are Live Concert 2022, were interviewed by police last week.

Officers also spoke to the engineers responsible for inspection of stage sets before the show.

Dancer Mo Li Kai-yin, 27, who suffered serious injuries when the giant screen hit him and who risks being paralyzed from the neck down, regained consciousness over the weekend.

His father, pastor Derek Li Shing-lam, said on Sunday Mo Li, who underwent two major operations in the wake of the tragedy, was able to manage basic communication.

Chang Tsz-fung, 29, also injured by the falling screen, was discharged from the CUHK Medical Centre on Sunday.

A third dancer was said to have been injured during rehearsals for the shows.
