Amir Taleipour, 39, and his wife Mahnaz Harati, 36, were arrested in front of their seven-year-old daughter by intelligence agents who raided their home in Mashhad in December.
The couple has not been allowed to communicate with family members or access legal assistance since. Family members are caring for their daughter while the couple is in detention.
In early December, two sisters from Ahvaz, in the southwest part of the country, were arrested and assaulted in detention. Security personnel beat the sisters during interrogation at security offices in Ahvaz. Prison authorities called to report the beatings to the family, and the sisters confirmed the physical assault in a phone call.
