The electricity company said the voltage dip happened at about 1.30pm, but there was no power interruption.

It said lifts might be suspended and there may be dimming or flickering in lighting systems nearby.

The Fire Services Department, meanwhile, said it received more than 120 reports of people being trapped in lifts between 1.30pm and 2pm.

It added that there were also about 30 cases of fire alarms going off. The department was conducting rescue operations and handling the incidents.
