Erabi's mother, Parvin Fahimi, had made numerous inquiries at prisons and courts since he disappeared, according to the International Campaign for Human Rights in Iran. On Saturday, she was finally called in by officials and asked to identify her son in several photographs of corpses.
"The lack of transparency and calculated delay in releasing the information about [Erabi's] unexplained death only raises anxieties about scores of others who are among the disappeared as well as those who have been held in incommunicado detention, with no contact to family members or lawyers, many for almost a month," said the group in a statement. "An additional approximately 190 persons were arrested following the most recent demonstrations on 9 July."
