New Delhi, July 10 -- In a setback for fugitive diamantaire Mehul Choksi, currently lodged in a prison in Antwerp, the Court of Cassation in Belgium - equivalent to the Supreme Court of India - has rejected his bail plea, which means he might have to stay in prison for a very long time, people familiar with the development said on Wednesday. The Court of Cassation's decision was delivered last week according to an officer who didn't want to be named, strengthens the Central Bureau of Investigation's case against Choksi and validates the evidence provided there in the courts. "The Court of Cassation didn't find Choksi's arguments for his release on bail convincing. He may not get relief very soon, even during extradition proceedings, which may not begin before September end," added the officer. Choksi, 65, was arrested by Antwerp police on April 11, based on an extradition request sent by CBI and has been lodged in the prison there for nearly three months now. The fugitive businessman's legal team refused to comment. According to the second officer, a CBI team recently travelled to Antwerp to provide additional information and evidence against Choksi and his companies. He is accused of defrauding Indian banks of Rs.13,000 crore before fleeing in January 2018....
