Former Goldman Sachs Group Inc. director Rajat Gupta is a free man after serving 19 months in federal prison for leaking tips to hedge fund billionaire Raj Rajaratnam.

Jailed in June 2014 in Devens, Massachusetts, Gupta was freed after receiving credit for good behavior against his 30-month sentence, according to Patrick McFarland, a manager for the Federal Bureau of Prisons program in the New York area which is overseeing Gupta. McFarland declined to provide more details

Under a U.S. Bureau of Prisons program called Residential Reentry Management, Gupta must spend his evenings at home, the person familiar with his case said. He’s also permitted to leave for doctors’ and lawyers’ appointments, but must get prior approval from prison officials.

Gupta was found guilty in 2012 of passing illegal tips to Rajaratnam, a co-founder of the Galleon Group LLC hedge fund. He told Rajaratnam about Berkshire Hathaway Inc.’s $5 billion investment in Goldman Sachs and the bank’s financial results for two quarters in 2008.
