Iran has arrested a member of the Central Council "Allied Front", Ali Shukuriad, Tehran City Prosecutor Abbas Jafari Dovlatabadi was quoted as saying by FARS.
However, Dovlatabadi did not specify what charges were brought against Shukuriad.
Last week, Shukuriad posted on his blog a critical article entitled "Judicial scandal: Mohsen Azhei must go" about the ex-security minister and representative of the Iranian judicial system ,Gulamhossein Mohsen Azhei, and the Prosecutor General.
Dovlatabadi added that the son of Iranian Advisory Council Chairman Ali Akbar Hashemi, Mehdi Hashemi, will also be arrested when entering the country.
Mehdi and Faiza Hashemi, the children of ex-Iranian president Ali Akbar Hashemi-Rafsanjani, have repeatedly been accused of provoking unrest in the country, as well as in organizing large-scale actions against the results of presidential elections held in June 2009.
