Okinawa police say the 24-year-old woman was detained after she failed to stop at an intersection. She collided with a car whose driver is said to be unhurt. Local police say the American worker’s alcohol level was four times the legal limit. The US military has prohibited its service members from drinking alcohol off base and outside their homes. The ban comes amid rising anger in Okinawa over crimes committed by the US military personnel. Last week, Okinawa demonstrators held another protest against the presence of the U-S military on their island. The protest was triggered by the rape and murder of a Japanese girl by an employee of the US base.
