Mwangi said he was held in Tanzania after going to the country to show solidarity with detained opposition politician Tundu Lissu. Boniface Mwangi said he had decided to speak despite the "shame and guilt of being sodomised with all manner of things". A Kenyan activist has told the BBC that he is "struggling to be alive" after allegedly being sexually tortured in detention in Tanzania last month. Mwangi told the BBC Newsday programme that the torture had left him in mental anguish. Mwangi told the BBC that their visit to Tanzania was to highlight Lissu's "sham case", adding that this "wasn't taken lightly" by the authorities.
