The 3,000 billion toman embezzlement scandal in Iran (also 2,800 billion embezzlement; approximately US$943.5 million) was a corruption scandal involving the use of forged documents to obtain credit from at least seven Iranian state and private banks to purchase recently privatized state-owned companies. The fraud reportedly extended over a four-year period, but became more serious in the months before the scandal broke in September 2011. According to Iranian newspapers, Iranian businessman Mahafarid Amir Khosravi (also known as Amir-Mansour Aria) masterminded the scam, and as of late October 2011, at least 67 people have been interrogated and 31 of them have been arrested, with Aria being executed in 2014.
