One of the co-founders of the Black Consciousness Movement, Strini Moodley, died at the age of 60 on Thursday morning after a brief illness, his family said in a statement.
"A friend and comrade of the late Steve Biko, he was one of the nine activists convicted on terrorism charges in 1976 following the marathon South African Student Organisation and Black People's Convention trial in 1976."
He was later convicted under the Terrorism Act and sentenced to six years' imprisonment, which he served on Robben Island.
He was a former deputy news editor at the Natal Witness.
Moodley was born on December 22 1945. He is survived by his wife, Asha, and four children.
The African National Congress offered its condolences to Moodley's family.
"As South Africa celebrates Freedom Day, we pay to tribute to a committed freedom fighter who dedicated his life to the liberation of the South African people and to the achievement of peace and justice in many other parts of the world," party spokesperson Steyn Speed said in a statement. -- Sapa
