A BAR known as an entertainment industry haunt in Causeway Bay and believed to be frequented by male prostitutes was raided by police early this morning. Officers from the Organised Crime and Triad Bureau arrested 14 men at the club, which is on the 17th floor of a residential building in Kingston Street. Suspected Sun Yee On gang members were among those detained. Detectives questioned customers at the club before escorting a group of suspects from the building shortly after 1.15 am this morning. A police source said detectives learned of the bar during investigations into the activities of the Sun Yee On gang.
