Largest Bank Fraud in Iran

I was reading about a huge corruption case in Iran. Thirty nine people have been convicted of a bank fraud/scam. Four bankers are set to be hanged.

Another banker, Mahmoud Reza Khavari, managed to dodge the bullet by fleeing to Canada.

Name of the convicted felons are not released to the public.

But one of the defendents complained that, while the judiciary had pursued some low-level players in the fraud vigorously, senior officials involved in the scandal had gone unpunished.

Based on comments from a news site, many seem to agree that it's about time people who are involved in bank frauds get harsher punishment than just a slap on the wrists.
