Police on Japan's Okinawa island have turned over to prosecutors a case involving a U.S. airman suspected of assaulting a teenager after a drinking binge.

The prosecutors will now decide whether to press charges against the airman, whose name had not been released as of Monday. Police believe he entered an apartment near a bar where he had been drinking, punched the boy in the face and tried to flee through the window.

The incident came shortly after all U.S. troops in Japan were put under a curfew following an alleged rape last month that sparked outrage on Okinawa, which hosts more than half of the 52,000 U.S. troops in Japan.

Another incident occurred Sunday, when a Marine who was reportedly drunk was arrested for sneaking into a woman's apartment.
