Japanese police have arrested a Marine lance corporal on suspicion of throwing a man to the ground and injuring him in a city near Tokyo.

Blake Allen Dequaine, 20, was in the custody of Kanagawa Prefectural Police on Tuesday, a police spokesman told Stars and Stripes by phone that day.

Police allege Dequaine threw a passerby, a 43-year-old man, to the ground around 12:30 a.m. Tuesday in the Nakahara ward of Kawasaki city, about 10 ½ miles southeast of Tokyo.

Dequaine was arrested about 10 minutes later, according to the spokesman. He said the passerby was injured but declined to provide further information.

Some government officials in Japan speak with the media only on condition of anonymity.

Dequaine is a rifleman with 3rd Battalion, 5th Marines, according to 3rd Marine Division spokeswoman Capt. Annika Pearson. He’s deployed to the 4th Marines, based at Camp Schwab, Okinawa, as part of the Unit Deployment Program.

Dequaine was in Kawasaki on liberty, Pearson said.

“The Marine Corps is aware of the incident and cooperating with local authorities,” she told Stars and Stripes by email Tuesday. “The alleged misconduct is not aligned with our core values, which the majority of Marines and Sailors uphold.”
