Nasser Kheyrollahi, aged 48, who attempted to expose official corruption, has been charged with vaguely worded offences which could see him detained as a prisoner of conscience. He is now held in Reja-i Shahr prison in Karaj, near Tehran, together with prisoners convicted of violent offences, where he has reportedly been tortured and ill-treated repeatedly and has recently had several bones broken. He reportedly began a hunger strike on 17 January to draw attention to his situation.
