In 1986, dozens of Kenyans were detained and accused of belonging to an underground opposition movement called Mwakenya. They were taken to Nyayo House - a government building in the centre of Nairobi - and secretly tortured. Many more were arrested by President Moi’s government in the years that followed. But it was not until he left office that the full details of Kenya’s torture chambers emerged. Witness speaks to Wachira Waheire one of the former detainees.
