Hong Kong police arrest 125 people in a crackdown on an alleged triad-run syndicate accused of controlling the lunchbox catering market for construction workers in East Kowloon. Police say the group targets food vendors and seeks to monopolise takeaway supply at construction sites by intimidation and extortion. The alleged activities include using violence and, in some cases, arson to corner the market and deter competitors. Police also say the syndicate operates illegal gambling dens alongside the catering scheme. The arrests are carried out through an undercover operation, with officers moving against the group that police describe as active in the area. Sources say the crackdown focuses on private and public housing building sites, where increased residential and construction projects have created demand for lunchbox services. Police do not indicate in the provided reports that the suspects include specific named individuals, but they describe the operation as targeting a triad structure seeking stable income from monopolising customers at worksites. The cases are presented as part of a broader effort to disrupt organised crime and unlawful gambling activity.
