Japanese news outlet NHK News Web reports that Index, parent company of game publisher Atlus, is under investigation due to suspicions of fraudulent accounting. The company's headquarters and individual employees' houses have been raided by police.
Details on the case are relatively thin on the ground right now, but it seems that the company is accused of "window dressing" - artificially inflating sales and the appearance of financial stability by repeatedly moving money around between companies. At present, it's looking more likely that this was going on on a personal rather than company-wide level, presumably to manipulate stock prices and skim money off the top for reasons currently unknown.
Representatives from Index were unable to comment on the situation due to the ongoing investigation. Atlus' Japanese Twitter account has confirmed that all currently-announced games will be released as scheduled. Let's hope that this is resolved quickly, though, otherwise we might be waiting a very long time to see Persona 5.
