The workers were stuck on the exterior of the building on Des Voeux Road Central at around 11am when the gondola malfunctioned, leaving the two stranded in mid-air.

It was said that the controller of the gondola was unresponsive following a power failure, with the workers unable to get themselves back to safety.

The Fire Services Department dispatched a rescue team to the scene after receiving the report. The duo was later rescued and brought to safety through an aerial ladder mounted on a fire truck.

This is the second gondola incident within a month in the Central district, with two workers trapped in cleaning gondola at Standard Chartered Bank Building on April 20.
