Apple Europe internal investigation underway?

Chalk this one down to uncorroborated rumor (and perhaps even a wretched April Fools joke) but notorious leak merchants Hardmac have been told that Apple Europe are currently undergoing an internal investigation that's apparently "way beyond" the scope of previous audits.  According to their anonymous source, Apple are looking through all records "as if they were aware of some information or details" and were trying to find proof to substantiate it.

So far nobody bar the Apple investigators know what it is exactly that has prompted the audit, and it's unlikely that any more information will emerge until the process has finished.  Apple are notoriously secrecy-sensitive, and the company is known for disseminating fake information or differing copies of documents so that they can more easily identify the source of leaks.
