WASHINGTON (AP) _ A Chicago-area man accused of guarding a facility where Jewish men, women and children were executed during World War II has left the United States for Lithuania, the Justice Department announced today.

Vincas Valkavickas, 78, agreed to leave rather than face a civil trial in immigration court for assisting in the persecution of civilians as a member of the Lithuanian Auxiliary Police.

Valkavickas left the United States under an agreement admitting that in 1950 he concealed and misrepresented his service with the police. The Justice Department's Office of Special Investigations initiated the case against Valkavickas in immigration court last September.

Auxiliary police battalions were created by the Nazis in 1941 to assist with the German occupation of Lithuania. The Justice Department said that in two days in October 1941 in Sviencionys, Lithuania, Valkavickas was on duty at a former military installation known as the Polygon where 3,700 Jews were executed by gunfire.
