Yomiuri Shimbun, one of five national Japanese newspapers, is reporting via its English 'The Japan News' website that of the 650,000 bitcoins that went missing in the aftermath of the Mt. Gox collapse, 99% of the coins have been lost due to the fraudulent activities by an unknown individual or party. An additional 7,000 bitcoins are reported to have been stolen due to cyber-attacks.
The article continues by stating that the Tokyo Metropolitan Police Department suspect that someone familiar with the exchange may be responsible for the misappropriation of the lost bitcoins and that more information will be published in the January 3rd 2015 print edition of the newspaper.
The Yomiuri Shimbun, a daily newspaper, was founded back in 1874.
