Bloomberg reports, here, that a US Marine was arrested by Japanese authorities in Okinawa
[O]n suspicion of breaking into the house of a woman in her 20s and sexually assaulting her, police spokesman Motoki Haneji said by phone. The U.S. serviceman has denied the charges, Haneji said.
As N-M JAs know, these arrests have led to protests and were a part of the discussion that led to the reorganization of the US military presence in Japan. The Japanese have primary jurisdiction over the case and prior cases have been handled by Japanese courts.
