Fugitive diamantaire merchant Nirav Modi on Wednesday cited poor conditions of Indian jails and increased “risk" of depression that may lead to suicide as arguments in a fresh appeal against extradition in the UK. During the “renewal application” hearing before Justice Martin Chamberlain, Nirav’s lawyers sought to establish the grounds for a full High Court appeal hearing by claiming it would be oppressive to extradite him due to his mental condition that could lead to suicidal impulses.
