TOKYO — A sailor who returned from Operation Iraqi Freedom last week was arrested Saturday night after injuring two Japanese men.

Airman Nathaniel W. Horn, 21, was arrested as the incident took place in a Yamato city restaurant around 4 a.m. on Friday, a Kanagawa prefecture police spokesman said.

Contacted Sunday afternoon, a Commander, Naval Forces Japan spokesman neither confirmed nor denied the report. A Kitty Hawk spokesman said Horn is not an assigned ship’s crew member.

The police official said that an intoxicated Horn walked into the restaurant, then soon exited. He then broke a window from outside with his bare hand, police say.

Two Japanese men tried to restrain him and the sailor injured them both, the police spokesman said. One of the men had a cut face; the other, a broken finger.

The sailor returned May 6 “to Atsugi from the war in Iraq, where he checked the wings of aircraft on the Kitty Hawk,” the police spokesman noted.

As of Sunday afternoon, it was the lone incident Japanese authorities had reported involving U.S. sailors since about 13,000 from the USS Kitty Hawk battle group and the visiting USS Carl Vinson battle group arrived at Yokosuka Naval Base last week.

Horn was to remain in Japanese police custody until prosecutors review the case, the spokesman said.
