Mt Gox’s Mark Karpeles arrested in Japan

French-born Mark Karpeles, head of the failed Mt Gox Bitcoin exchange, has been arrested in Japan.

The arrest comes eight months after Japanese police said they were confident the incident that saw most of the Bitcoin held by Mt Gox evaporate was the result of fraudulent transactions.

Karpeles had previously claimed the lost Bitcoin – worth hundreds of millions of dollars – were stolen in cyber-attacks, which led to the collapse of Mt Gox.
