A D.C. police officer assigned to the department's prostitution task force was sentenced to a year in prison yesterday for sexually abusing a prostitute.

Vincent Andrews, 32, was given a sentence of two to six years with all but one year suspended, according to the U.S. attorney's office. D.C. Superior Court Judge Ronna Lee Beck, who handed down the sentence, also ordered Andrews to serve two years' probation at the end of his prison term and to perform 300 hours of community service. The U.S. attorney's office had requested a 12- to 36-year prison term.

Andrews was convicted in September of first-degree sexual abuse of a ward, tampering with evidence, obstruction of justice and assault after he arrested a prostitute, processed her, then drove her to a secluded location and ordered her to perform oral sex.

Andrews then took the woman to the 3rd District station and told her to turn over the condom he had worn. When she refused, he attacked her in front of two other police officers, claiming the woman had drugs. Andrews pulled off her pants, ripped off her panties, grabbed the condom that she had hidden and ran to a bathroom.

The condom was never found, though a condom wrapper was found where the woman said the two had sex.

Andrews, who has been on the force since 1989 and remains on administrative leave without pay, will be terminated from the department, an official said yesterday.
