The court convicted 22-year-old Lance Cpl. Jamel Clayton of "nonconsensual sexual intercourse causing injury," according to a spokesperson for the Marine Corps.

A Japanese found a U.S. Marine guilty of sexually assaulting a woman on Okinawa in a case that has triggered anger and safety concerns​ on Okinawa, which has a heavy American troop presence.

Lance Corporal Jamel Clayton, 22, attacked and choked the woman from behind and tried to have sex with her, the Naha district court in Okinawa said on Tuesday. The woman, in her 20s, had reported the assault to the local police as well as a friend shortly after it took place in May last year.
