Police have found no sign of arson in the Klongthom Shopping Centre fire on Worachak Road, and the cause will not be settled until forensic and structural checks finish. Traders and business operators are still barred from the site because the building is unsafe, and the BMA is preparing for eventual demolition. If you have stock or fixtures in the market, file a damage complaint with police and keep records of losses; expect a wait before you can retrieve goods.
