From this article, I can't seem to find where the Prosecutor ever said there was "new" information.
Only the headline and the commentary on the statement makes that claim.
Perhaps I missed it. Does anyone have the statement they released?
Only the press. It'll appear to the general public here ... http://www.sao4th.com/.
Typical press report characterization is, "a news conference 'within the next 72 hours' to release new information regarding the investigation."
