Raj Rajaratnam, accused of insider trading, was released on a record breaking $100 million bail after his arrest last week on charges of conspiracy and securities fraud. Rajaratnam arrived at work this morning, just three days after being released from federal custody reports TBI.

On Friday, employees at the hedge fund Galleon were told to conduct “business as usual.” Rajaratnam appears to be leading by example.

Meanwhile it looks like the authorities are going beyond their usual with extensive charges in the pipeline, some of which are linked to the Rajaratnam case; from Bloomberg:

The pending crackdown, based on at least two years of investigation, targets securities professionals including hedge- fund managers, lawyers and other Wall Street players, the people said, declining to be identified because the cases aren’t public. Some probes, like the one that focused on Rajaratnam, rely on wiretaps. Others stem from a secret Securities and Exchange Commission data-mining project set up to pinpoint clusters of people who make similar well-timed stock investments.
