A son of prominent South African anti-apartheid activist Steve Biko has told the BBC the family is confident a new inquest into his death 48 years ago will lead to the prosecution of those responsible.
Seen as a martyr in the struggle against white-minority rule, the Black Consciousness Movement founder died from a brain injury aged 30 almost a month after being arrested at a road block.
Police at the time said he had banged his head against a wall, but after apartheid ended in 1994, former officers admitted to assaulting him - although no-one has been prosecuted.
Nkosinathi Biko, who was six when his father died, said the country could not move forward without addressing its violent past.
"It's very clear in our minds as to what happened and how they killed Steve Biko," he told the BBC after the first hearing was held at the High Court in the southern city of Gqeberha - on the 48th anniversary of his father's death.
