Hong Kong authorities have arrested 21 individuals in a crackdown on corruption within the building renovation sector. The Independent Commission Against Corruption (ICAC) targeted middlemen, consultants, contractors, and owners' corporation members across two housing estates. Suspects allegedly engaged in bribery to secure contracts worth millions and manipulated votes using authorization tickets. This operation follows a recent independent committee formation by city leader John Lee to investigate the construction industry and potential bid-rigging, spurred by a deadly fire in November attributed to substandard materials.
