Iran frees grandson of powerful ex-president

The Tuesday report by Fars quotes prosecutor Abbas Jafari Dowlatabadi as saying authorities Monday released Hasan Lahouti after it interrogated him. He was freed on a $73,000 bail.
Fars said Monday that Hasan Lahouti was arrested at Tehran airport upon arrival from London late Sunday.
The Monday report did not say why Lahouti was detained.
Rafsanjani, a powerful figure in Iran's clerical establishment, supported opposition leader Mir Hossein Mousavi in his challenge to President Mahmoud Ahmadinejad, who the opposition says won June elections by fraud.
