Police in Kanagawa Prefecture said Wednesday they have arrested a 33-year-old American man who assaulted two passengers on a train in Yokosuka.

According to police, the incident occurred inside a stopped train at Keihinkyuko Shioiri Station at around 11:30 p.m. on Jan 12. TV Asahi reported that the suspect, Darrell Raymond Sheppard, bashed a 29-year-old male passenger in the face causing several broken bones and requiring the victim to spend one month in hospital. After a 21-year-old American serviceman, who witnessed the attack, attempted to restrain Sheppard, he was pushed onto the platform and knocked down.

Police said Sheppard, who dropped his cell phone at the scene of the crime, was also on Interpol's wanted list for aggravated sexual assault in the United States and is likely to be extradited back to the U.S.

Police said they have begun an investigation into how and where Sheppard entered Japan.
