Reports from Tehran indicate that a number of participants in campaign events for reformist presidential candidate Hassan Rohani were arrested on Saturday in Tehran.

Saham News reports that a number of Rohani’s campaign workers were arrested yesterday along with a number of people who protested their arrest at an official gathering.

The identities of the detainees have not been announced yet; however, the Neday-e Sabz-e Azadi website reported the arrest of Amin Vatani, a student activist at Saturday’s gathering who was reportedly beaten prior to his arrest.

The presidential election will take place this week, and two reformist candidates, Hassan Rohani and Mohammadreza Aref, are expected to announce soon if one will withdraw in favour of the other.
