A U.S. sailor was arrested Sunday on suspicion of drunk driving in Okinawa, where a U.S. base worker's alleged involvement in the death of a local woman last month has reignited anger among residents.

The three-vehicle accident, which injured two people, prompted the Defense Ministry to lodge a protest with Lt. Gen. Lawrence Nicholson, the U.S. military commander in Okinawa, and occurred on the same day as the prefectural assembly election.

Arrested by the Okinawa Prefectural Police was Petty Officer 2nd Class Aimee Mejia, 21, who is stationed at Kadena Air Base.
