2019.08.11 Police fired tear gas into an enclosed space (Kwai Fong MTR Station)

Despite clear warning from manufacturers against indoor use, police fired tear gas inside an MTR station which practically created a gas chamber in the station with no escape route, it completely defeats the purpose of crowd dispersal.

Even with clear video evidence of tear-gassing from multiple media sources, police claimed to have never fired in the MTR station. This is yet another example of flat-out lies by the Hong Kong Police Force.
