The care one must take to not be arrested or detained during time traveling cannot be overstated. Though, what was not reported was his rescue less than 24 hours later by a team of time travelers who infiltrated the Swiss military installation where he was being held for questioning by EU officials.
The lesson here is to have some kind of backup. The buddy system is one way to travel. Always make sure someone—your partner—from your time knows where and when you are going, and expects to see you at some predetermined meeting location and time. In the event that you do not show up for the meeting, your partner will then initiate a search.
