The management of Mega Bangna shopping centre in Bang Phli district of Samut Prakan have explained why an escalator suddenly stopped working on Tuesday.
The incident was accompanied by a loud noise and alarmed some customers, one of whom posted about it on Facebook.
The statement said the incident occurred at 4.51pm and was caused by an object that dropped onto the moving staircase and blocked its movement. This caused the safety switch to cut off the system, in line with safety standards.
The loud noise might have caused some alarm, but nobody was hurt.
The escalator was temporarily suspended from use while it was inspected and fixed.
All equipment used at the shopping centre was regularly checked and maintenance carried out, the statement said.
The management welcomed opinions and constructive advice to improve its services, the statement said.
Public concern about the safety of moving walkways has been heightened since an incident last month at Don Mueang Airport, where an accident on a travelator cost a 57-year-old woman a part of her left leg.
Airports of Thailand has ordered a thorough investigation by experts and is expected to release a public report soon.
