Mt. Gox
CEO Karpelès was arrested in August 2015 by Japanese police and charged with fraud and embezzlement, and manipulating the Mt. Gox computer system to increase the balance in an account—this charge was not related to the missing 650,000 bitcoins. After he was interrogated, Japanese prosecutors accused him of misappropriating ¥315M ($2.6M) in bitcoin deposited into their trading accounts by investors at Mt. Gox, and moving it into an account he controlled, approximately six months before Mt. Gox failed in early 2014.
