A 36-year-old man was in critical condition after he was hit by a large wooden board he and his co-workers were trying to transport on an elevator in a Hong Kong shopping mall on Monday.

At 11:30am, the victim and three colleagues were attempting to transport the board, measuring 2.6 by 2.3 meters, from the ground floor to a handbag shop on the B1 floor at Langham Place shopping mall in Mong Kok, Kowloon, Sing Tao Daily reported.

The workers carried the board, which weighed about 50 kilograms, on the escalator but it was too big and hit the ceiling, then fell on one of the men, injuring his head.

A passer-by said the other workers, assisted by three security guards at the shopping mall, tried to lift the board off the victim but failed.

Finally police and firefighters rescued the victim but he was unconscious when he was sent to hospital. He was listed in critical condition after resuscitation.

A Langham Place official said workers were not supposed to use the escalators for moving things around, but should use the freight elevator.

In 2017, 18 people were injured in Langham Place when an escalator, one of the longest in Hong Kong, suddenly stopped and reversed direction.
