'Shark Tank's Daymond John has filed a restraining order against former contestants, following allegations that he's taken over their business, Bubba Q's Boneless Baby Back Ribs. In a statement to ET, a rep for the entrepreneur denied the claims, adding that the legal move comes after 'blatant actions to undermine a business partnership and the legal parameters they agreed to 4 years ago.' The contestants first appeared on season 5, episode 11 of ABC's reality series in 2013.
