A whistleblower who exposed the torture of protestors in Iranian jails has died after being poisoned by a delivery salad laced with blood pressure medication, fuelling fears that he was murdered. Ramin Pourandarjani, a 26-year-old doctor, died last month and investigators are still trying to determine if his demise was suicide or murder. “The revelations of torture against prisoners in Iran's postelection turmoil angered even government supporters and deeply embarrassed the country's clerical leadership and security forces…[Pourndarjani] testified to a parliamentary committee and reportedly told them that a young protester he treated died from severe torture. He said he was also forced by security officials to list the cause of death as meningitis, according to opposition Web sites.”
