It appears that the fraud at Satyam Computer services – initially thought to be about $1,5-billion – could actually be at least $1-billion more.

Inevstigators this week said founder Ramalinga Raju understate the amount when he confessed to the fraud in January this year
In January Raju explained how the error grew from a small discrepancy years ago into the massive fraud it became.
"What started as a marginal gap between actual operating profit and the one reflected in the books of accounts continued to grow over the years," he wrote then. "It has attained unmanageable proportions as the size of company operations grew. It was like riding a tiger, not knowing how to get off without being eaten."
Later, Raju was arrested for cheating, forgery, criminal breach of trust and falsifying documents.
