Kolkata, Nov 30 (ANI): Chief of Sahara conglomerate, Subrata Roy has said that he is ready to face challenges posed by the entire country to come clean on the valuation of its properties or liabilities to government regulatory bodies. Addressing a conference in Kolkata, Roy said that he is ready to be hanged if anyone can prove the charges against his group. Often dubbed as a billionaire by the Indian media, the Sahara chief had earlier been locked in a battle with the market regulator, Securities and Exchange Board of India (SEBI), over a bond scheme that the apex court deemed to be illegal, and was ordered by the regulator to provide details of his personal assets and two Sahara companies. Earlier this week, the apex court had barred Roy from leaving the country. His group had also been forbidden from selling any of its properties till the time the group would provide necessary documents to SEBI.
