The Hospital Authority (HA) said one of the two dancers injured in the MIRROR concert accident on Thursday remains in serious condition, while the other has been discharged from hospital.

In a statement released on Friday, the HA said the dancer who was seriously injured, is being treated at the Intensive Care Unit of Queen Elizabeth Hospital.

It added that he underwent an operation on Friday afternoon.

The other dancer who was in a stable condition, meanwhile, has been discharged from the hospital.

The two were hit by a large video screen which came loose and fell to the stage during the concert at the Hong Kong Coliseum.

"The Hospital Authority is aware of the information related to the injured being widely spread through society, [but] the HA could not disclose further details of their conditions in order to protect patient privacy," the statement wrote.

"The medical team will closely monitor the condition of the injured persons, providing appropriate treatment, support and follow up on their recovery."
