Timeline to the Discovery of India's Biggest Ever Bank Fraud

(Bloomberg) -- India’s second-largest state-run lender this month disclosed it has been hit by the nation’s biggest ever bank fraud.

Billionaire jeweler Nirav Modi and his associates colluded with a rogue employee at Punjab National Bank to obtain fraudulent guarantees worth $1.8 billion dollars over seven years, PNB alleges. They then used these documents to obtain loans from lenders abroad, according to PNB’s complaint, which has been made public.
