The Labour Department is investigating an accident at a construction site in To Kwa Wan, in which a worker died after being hit by a fork-lift truck on Tuesday morning.

The accident happened at about 9am at the building site near Kowloon City Ferry Pier.

The 49-year-old male victim had been helping to reposition a power-operated elevating work platform in a tunnel when he was struck by the fork-lift.

He was rushed to Queen Elizabeth Hospital where he was certified dead.

Officials have issued suspension notices to the contractor, stopping work carried out by the fork-lift truck at the site and the repositioning of the work platform.

"We will complete the investigation as soon as possible to identify the cause of the accident, ascertain the liability of the duty holders and recommend improvement measures. We will take actions pursuant to the law if there is any violation of the work safety legislation," the department's spokesman wrote in a statement.
