Japanese alternative operator KDDI has confirmed that the private details of nearly four million of its DION Internet customers have been leaked to a third party. The information divulged includes names, addresses and telephone numbers of 3,996,789 customers who applied for the service before 18 December 2003, although confidential data on bank details, passwords and private login codes were not released. It is understood that police in Tokyo have arrested two men in connection with the leak. Akio Minomura and Akihiko Torii are suspected of having attempted to extort between JPY5 million and JPY10 million from KDDI in exchange for the information they have obtained.
