Hong Kong 1967 Leftist riots refers to the large-scale leftist riots between pro-communists and their sympathizers, and the establishment. While originating as a minor labour dispute, the tensions later grew into large scale demonstrations against British colonial rule. Demonstrators clashed violently with the Hong Kong Police Force. Instigated by events in the People's Republic of China (PRC), leftists called for massive strikes and organised demonstrations, while the police stormed many of the leftists' strongholds and placed their active leaders under arrest. These riots became still more violent when the leftists resorted to terrorist attacks, planting fake and real bombs in the city and murdering some members of the press who voiced their opposition to the violence.
