New York ? South African poet and former political prisoner Dennis Brutus, who fought apartheid in words and deeds and remained an activist well after the fall of his country’s racist system, has died. He was 85.

Brutus’ publisher, Chicago-based Haymarket Books, said the writer died in his sleep at his home in Cape Town on Saturday.

Brutus was an anti-apartheid activist jailed at Robben Island with Nelson Mandela in the mid-1960s. He helped persuade Olympic officials to ban South Africa from competition from 1964 until apartheid ended nearly 30 years later.
