NEW DELHI: An Indian yoga guru has begun a mass anti-corruption protest demanding the government bring back billions of dollars of illegal money stashed in foreign banks.       

Tens of thousands of supporters from across the country poured into New Delhi on Thursday to pledge their support for Baba Ramdev's anti-corruption crusade. Ramdev says he will fast for three days to push for laws to wipe out tax evasion and endemic corruption in India.

India’s Central Bureau of Investigation says around $500 billion has been illegally squirreled away in overseas tax havens.

The protest comes less than a week after a similar protest by anti-graft crusader Anna Hazare ended with his supporters promising to enter politics.
