CAMP FOSTER, Okinawa — Japanese police jailed two Marines on Okinawa in separate incidents over the weekend at a popular nightlife district outside Kadena Air Base.

Okinawa police arrested Lance Cpl. Alfredo Francesco Rubinstein, 21, of Camp Schwab, at 2:22 a.m. Saturday after he allegedly grabbed a restaurant employee, age 58, by the neck and lacerated the man’s forehead, a police spokesman told Stars and Stripes by phone Monday.

A day later, Pfc. Adrian Jesus Martinez, 20, of Marine Corps Air Station Futenma, was detained after a woman said he grabbed her and threw her down, bruising her leg, the spokesman said.

Both Marines were held on suspicion of causing bodily injury, according to the spokesman. He said breath tests on both men measured their blood alcohol content at 0.12%, four times the legal driving limit in Japan. The men denied the allegations against them.

Both incidents occurred on Prefectural Road 20, an area of bars and restaurants known locally as Gate 2 Street, in the Chuo district of Okinawa city, the police spokesman said.

The Marines were still in police custody Wednesday, the police spokesman said that day. Some government spokespeople in Japan are required to speak to the media only on condition of anonymity.

Rubinstein, a machine gunner with 3rd Battalion, 6th Marines, was subdued by witnesses until police arrived, the spokesman said. Police referred Rubinstein’s case to prosecutors on Sunday.

Martinez, a Texas native and motor vehicle operator with Marine Air Control Squadron 4, was arrested at 3:21 a.m. Sunday, the spokesman said. A woman, 33, told police Martinez assaulted her after she scolded him for kicking a signboard on the street. Police referred his case to prosecutors on Monday.
