, Prosecutor General Gholam-Hossain Mohseni-Ejai announced Monday.
Borujerdi is the chairman of the Majlis National Security Committee and one of the most vocal denunciators of the United States to be found anywhere in the regime.
Ejai said Borujerdi and his son have not been arrested, just summoned for interrogation.
Some Tehran news reports have said several Majlis deputies have been implicated in the huge crime. They have named five deputies; in addition to Borujerdi, they are Arsalan Fathipur, Mo-hammad Dehgan, Jabar Koot-chakizadeh and Samad Marashi.
Ejai did not address the other four. Deputy Gholam-Reza Assadollahi, who serves on the committee investigating the embezzlement, last week said four deputies, whom he did not name, had been interrogated.
Ejai said the managing director of the Ahvaz steel foundry had been arrested in connection with the fraud. That foundry is believed to be one of the businesses privatized by the government that was bought as part of the fraud using funds illicitly procured as loans from about eight banks.
