The condition of a dancer seriously injured at the MIRROR concert in July improved on Tuesday.

Lee Kai-yin is now said to be in stable condition instead of serious in the nuerosurgery ward at Queen Elizabeth Hospital.

He was struck by a giant video screen that crashed down on the stage during the concert on July 28 at the Hong Kong Coliseum.

His father, pastor Lee Shing-lam, said a few days ago that his son had accepted the fact that he will spend a long period of time recovering in hospital.

The news of his improvement came as sources told RTHK that police detectives had conducted searches at several places connected to the concert, including firms involved in its production.

Pastor Lee, meanwhile, wrote on social media that he's refusing any donations for his son before a probe decides which parties should be held responsible.

Richard Li, the chairman of PCCW - the parent company of concert organiser MakerVille - said on Monday that he intended to personally donate HK$10 million to the family.

The pastor said his family is thankful for the good intentions, noting that besides the billionaire, there had been churches and other individuals that offered to raise money or provide treatment to the dancer.

The father, however, wants to wait until the government completes its investigation of the tragedy.

"Before the responsible parties are properly decided [by the government's probe], all donations would be too early. Please allow us to politely refuse the good intentions with a thankful and humble heart," he wrote in a Facebook post.
