Iran police says one of the perpetrators behind a deadly bomb attack on the headquarters of the Islamic Republic Party (IRP) back in 1981 has been arrested.

The assailant is a member of the terrorist�Mujahedin-e Khalq Organization (MKO) and was arrested in Albania with the collaboration of Interpol, said Iranian police spokesman Saeed Montazerolmahdi�during a press conference on Saturday.

He added that the perpetrator would�soon�be transferred back to Iran.

On 28 June, 1981, a powerful bomb went off at the IRP�headquarters, where the party�s leaders were holding a meeting. Tens of Iranian officials, including then Head of Supreme Judicial Council Ayatollah Mohammad Beheshti,�were killed in the bombing�by the MKO.

The MKO has carried out numerous terrorist attacks against Iranian�civilians and government officials over the past three decades. Out of the nearly 17,000 Iranians killed in terrorist attacks since the victory of Iran�s 1979 Islamic Revolution, about�12,000 have fallen victim to MKO's acts of terror.

Washington and the European Union have removed the MKO from their lists of terrorist organizations. The anti-Iran terrorists enjoy freedom of activity in the US and Europe, and even hold meetings with American and EU officials.
