The boy was on the escalator going down from the first floor heading towards the KTM station at 4pm when the mishap occurred. His foot was said to be trapped in between the metal panel and the stairs.
The victim was rushed to the Kuala Lumpur hospital for treatment. Two hours later, the Fire and Rescue Department was called to assist in finding the remainder of the foot, believed to be stuck in the escalator.
City Fire and Rescue Department assistant director (operations) Azizan Ismail said as of 7.20pm, his team was still in the midst of finding the foot.
The escalator has been halted following the incident. It was later learnt that the rescue team had recovered half of the trapped foot.
The incident prompted the Department of Occupational Safety and Health to issue a warning for parents and guardians to be alert when children wearing sandals or soft-soled rubber shoes ride escalators as such footwear can easily be caught between its steps.
