Japanese police arrested a 20-year-old U.S. Marine on suspicion of robbing and killing a 39-year-old woman at a hotel in Naha, the capital of Okinawa prefecture.

The suspect, identified by Japanese media and several international outlets as Lance Cpl. Devin Jacob Ballard, is accused of killing Anna Yagi and taking her wallet and backpack. He has denied the allegations.

Yagi’s body was discovered early Saturday in a hotel room. Kyodo News reported, citing police, that she appeared to have been strangled. Japanese media said security-camera footage showed a foreign man entering the hotel with Yagi and later leaving alone with what appeared to be her belongings. Police subsequently detained a man matching the suspect’s description.

The U.S. Marine Corps confirmed that a member of the III Marine Expeditionary Force stationed at Marine Corps Air Station Futenma was in Japanese custody. It said it was cooperating with Japanese authorities and extended condolences to Yagi’s family.

Japan lodged a formal protest and summoned U.S. Ambassador George Glass. Prime Minister Sanae Takaichi called the alleged crime “extremely brutal and heinous” and demanded maximum cooperation with the investigation, stricter discipline among U.S. personnel and measures to prevent similar incidents.

Glass offered condolences and pledged full cooperation. Okinawa Governor Genta Koja said repeated measures intended to improve discipline among U.S. forces had been ineffective. Okinawa hosts a large share of the approximately 54,000 U.S. military personnel stationed in Japan.
