On 27 September 1989 the Government of South Africa informed the Special Rapporteur that the 12 juveniles had indeed been detained at that time under the State of Emergency arising from violence perpetrated in the Pietermaritzburg area. They had subsequently been released. The South African Ministry of Law and Order rejected allegations contained in the second part of the appeal as false and malicious. It was prepared to investigate any substantiated allegations of that nature, but no facts had been produced by anyone alleging such torture and deaths. 135. On 19 July 1989 the Special Rapporteur addressed a letter to the Government of South Africa transmitting information concerning a 21-year-old student named Exodus Gugulethu Nyakane, of Wattville, who appeared in court in March 1989 in connection with the inquest into the death in custody of student leader Caiphus Nyoka. Mr. Nyakane made an affidavit in which he alleged that, following the killing of Caiphus Nyoka, he was taken, together with two other students named Elson and Excellent, to the Daveyton police station, where he was tortured by a white policeman. The torture consisted of burning hair at the back of his head and pouring boiling water down his back. Torture and ill-treatment reportedly continued the next day when Mr. Nyakane was allegedly shut in a locker and subjected to tear-gas fumes which almost suffocated him.
