TOKYO, Nov 2 — Japan urged the United States to enforce discipline among its troops after a Marine was arrested on suspicion of drink driving during a curfew in the wake of another serviceman’s arrest on a murder charge, the defence minister said today.

US forces on the Japanese island of Okinawa were barred from drinking alcohol for two days early last month and faced a 30-day curfew after the murder of a woman allegedly committed by an American Marine.

The case has triggered outrage in Japan and reignited controversy over the heavy US military presence on the southern island.

A second Marine had been arrested over allegations he drove under the influence of alcohol, Defence Minister Shinjiro Koizumi said.
