TEHRAN, July 2 (Xinhua) -- Iran's Police Chief Brigadier General Ismail Ahmadi Moqaddam said that some 1,032 people were detained during post-election unrests in Tehran, the semi-official Fars news agency reported on Thursday.

    Speaking to reporters here on Wednesday, Ahmadi Moqaddam said that most of the detainees have been released, and "those who are still in detention have been sent to the public and revolutionary courts in Tehran."

    "The police action towards the illegal gatherings staged during the final days of the unrests was completely legal ... and (the police) succeeded in controlling the unrests with the least violence," he was quoted as saying by Fars.

    On June 13, the Iranian interior minister said the incumbent President Mahmoud Ahmadinejad won 62.63 percent of the total ballots, while his main rival Mir-Hossein Mousavi got 33.75 percent.

    The other two candidates, former parliament speaker Mehdi Karroubi and former Revolutionary Guards Chief Mohsen Rezaei, got less than 2 percent of the total ballots.

    After the official declaration, all the three defeated candidates filed complaints over irregularities in the election, while Mousavi and Karroubi have demanded an annulment of the election.

    Mousavi's supporters participated in massive rallies in Tehran and other cities following the disputes.

    Iran's state media said 20 people had been killed in related clashes.
