The government lodged a protest Friday with Washington over the reported break-in and assault by a U.S. serviceman in Okinawa, an incident that comes less than three weeks after a high-profile alleged rape by two U.S. sailors of a woman in the prefecture.

According to the Okinawa Prefectural Police, a drunken member of the U.S. Air Force from the Kadena base become violent at a bar in the village of Yomitan around 1 a.m. Friday, violating a new curfew imposed in the wake of the alleged rape. The man's name is being withheld by Japanese authorities.

The suspect reportedly broke into an apartment on the third floor of the building housing the bar and, while trying to flee, struck a 13-year-old boy. The man reportedly then jumped off the third floor and as of Friday evening was being treated at a U.S. Navy hospital in Okinawa for injuries sustained in the fall.
