The elderly mother of a blogger who died in custody in 2012 was assaulted by unknown individuals in Iran on Thursday when she was on her way to visit her son’s grave.

Gohar Eshghi, mother of Sattar Beheshti has been demanding justice for her son who was arrested by security forces on October 30, 2012, for his blogging activity and died a few days later, in what was believed to be a case of torture in detention.

Just before noon on Thursday Eshghi was on her way to the cemetery when two people approached on a motorcycle and one of them attacked the elderly woman knocking her to the ground. People who saw the incident took her to a hospital, with injuries, a statement released by Sattar Foundation on Instagram announced.

The statement says that one month ago security agents had detained the family to prevent them from joining other victim families from a gathering. During that arrest agents threatened the family that some people die in prison under torture, but some could also die from an accident or in an altercation. After the incident the family kept receiving anonymous threats.
