On Saturday, Mark Karpeles, CEO of bankrupt bitcoin exchange Mt. Gox, which collapsed spectacularly last year, was arrested in Tokyo on suspicion of illicitly stealing $1 million from the online financial platform, the New York Times reports.

In the wake of Bitcoin exchange Mt. Gox announcing that it lost $473 million worth of the virtual currency, many people who saw their money disappear have called for CEO Mark Karpeles to be imprisoned. Well, funny thing: it wouldn't necessarily be the first time Karpeles has been arrested for fraud.
