TEHRAN, Iran (AP) — Iranian media say the son of influential former President Akbar Hashemi Rafsanjani has been released on bail.

Several papers, including the pro-reform Etemad daily, say Mahdi Hashemi was released late Sunday and immediately went to his father's home.

Authorities arrested the younger Hashemi in late September, a day after he returned to Iran from Britain.

He is held on charges of fomenting unrest in the aftermath of Iran's disputed 2009 presidential election that brought President Mahmoud Ahmadinejad a second term in office. Hashemi also faced corruption charges.

His arrest came days after his sister, Faezeh, was taken into custody to serve a six-month sentence on charges of making propaganda against Iran's ruling system.

Since Rafsanjani backed Ahmadinejad's reformist challenger in 2009, his family has come under pressure from hardliners.
