The Okinawa Prefectural Police on Saturday asked the U.S. Marine Corps in Okinawa for permission to conduct on-site investigations into the crash of a helicopter at Okinawa International University.
U.S. military personnel continued to investigate the site in Ginowan where a CH-53D transport helicopter from the Marine Corps' Futenma Air Station crashed Friday into a university building before exploding and bursting into flames.
Under the Japan-U.S. Status of Forces Agreement, which governs the management and operation of U.S. troops in Japan, Japanese investigative authorities need U.S. military approval to conduct investigations into U.S. military assets.
