An Iranian pro-reform Web site says authorities have released a former senior official detained for suspected involvement in the country's postelection turmoil, AP reported.
Parlemannews says former deputy interior minister Mostafa Tajzadeh was freed late Wednesday.
Tajzadeh was arrested June 13, a day after the country's disputed election that won President Mahmoud Ahmadinejad a second 4-year term.
He was among more than 100 political figures and activists who were put on a mass trial following the crackdown on opposition supporters who claim Ahmadinejad won by fraud.
The release comes ahead of the Iranian New Year later in March, when authorities traditionally release some prisoners in a symbolic act.
