Details are remarkably scarce at this stage, and it's entirely unclear what police were looking to find at Toyota HQ. According to Reuters, Toyota has been completely quiet on the subject of the raid. It seems logical that police would execute a search on Hamp's office in a bid to find any additional illegal medication, but that is, of course, pure speculation.
Hamp has been in headlines since June 18, when Tokyo police arrested her at her hotel. Allegedly, 57 pills of Oxycodone, a powerful, highly addictive, and easily abused painkiller, was sent to Hamp from the US. And while it may have been obtained here in the States with a legal prescription, that doesn't change the fact that it, along with some over-the-counter medications, remain illegal under Japanese law.
The embattled exec has had some big-name support since her arrest, though. Akio Toyoda, the head of Toyota Motor Corporation, stepped out on Sunday and said, "We are confident...that once the investigation is complete, it will be revealed there was no intention on Julie's part to violate any law."
Thus far Hamp has claimed ignorance, although that might not protect her from what one expert told Reuters could result in years in prison. Should any additional information become available, we'll be sure to update this post.
