17 December 1982
Around 100 African National Congress (ANC) members were reported to have been detained in Swaziland. The arrests were confirmed by the Swaziland Police Commissioner and a large cache of arms in the north of the country was found. The 1980s period was one of bitter times in the history of the movement in Swaziland.  A number of events, including a shootout between Swaziland police and ANC guerrillas marked the period. Following the shootout, the ANC’s Chief Representative in Swaziland, Stanley Mabizela and the police commissioner were summoned by King Sobhuza II to the Royal Kraal to negotiate a truce. Nonetheless, in 1982 Mabizela was forced to leave Swaziland following a secret agreement signed between King Sobhuza II and the South African government.
