TOKYO (AP) — Japanese police arrested a U.S. Marine in the alleged robbery and murder of a woman on Okinawa, officials said Sunday, the latest criminal case on the southern island where the heavy American troop presence has remained a sensitive issue.

The Okinawa prefectural police said they arrested a 20-year-old Marine stationed at the Futenma Air Station on suspicion of killing a 39-year-old local woman at a hotel in Naha, Okinawa’s capital city, and taking her wallet and backpack in the early hours of Saturday.
