The former chief of pediatrics at Fort Belvoir and a clinical psychologist have had their licenses suspended by the Virginia State Board of Medicine because of criminal sex charges brought against them.

The board, which licenses health care practitioners, last week announced the indefinite suspension of Dr. Arthur C. Andreasen of Alexandria, who is facing charges of sodomy and forceable sexual battery. It also indefinitely suspended clinical psychologist Peter O. Heinemann of Alexandria, who pleaded guilty in 1979 to a misdemeanor charge of indecent exposure.

Andreasen, 40, was indicted Jan. 6 on a charge that he forced a 15-year-old boy to commit sodomy during a physical examination at a private health clinic in the city. He is awaiting trial in Alexandria Circuit Court.

Andreasen consented to the indefinite suspension of his license, according to the medical board.

In Heinemann's case, the state board said it acted after it discovered that the 44-year-old psychologist had been convicted in 1979 in Fairfax County of a misdemeanor involving moral turpitude. Heinemann received a suspended jail sentence.

Federal officials are conducting a criminal investigation into the Army's 1983 decision to let Andreasen, then chief of pediatrics at Fort Belvoir, resign even though a Defense Department investigation found enough evidence of alleged sexual misconduct for a court-martial.

A 1984 Defense Department investigation of the Army's handling of charges of sexual improprieties against Andreasen found that the decision to allow him to resign without prosecution could condone the "release of highly questionable physicians into an unsuspecting civilian medical community."

Andreasen joined the Kaiser-Permanente health organization after leaving the Army but later resigned.
