Two brothers behind a popular brand of craft chocolate have apologized for 'misleading' customers after they were accused of 'defrauding the public' by allegedly covering-up how some of their bars used to be made. Rick and Michael Mast, who both sport impressive beards, launched Mast Brothers chocolate in New York in 2007. Their range, which costs up to $23 (£16) a bar, is now on sale at flagship stores in Brooklyn, New York, and London's trendy east end.
