When Iranian student activist Arash Sadeghi was temporarily released from Tehran's infamous Evin prison in November 2010, he anticipated a little respite from a year of harsh beatings and agony in jail.
Instead, within a few days, security officials had raided his home in middle of the night. As they broke their way into the house, Sadeghi's mother, who was alone with her daughter, suffered a heart attack.
The officials continued their search as she laid unconscious on the floor, ransacking the house and trying to find Sadeghi, who was at his grandfather's house that night. When the officials left, Farahnaz Dargahi was taken to hospital. She died within a few days.
