Tribune staff report

NAPERVILLE - A Naperville councilman acquitted of battery and disorderly conduct this year filed suit Wednesday against the city, police chief and two officers, alleging they filed false charges against him as political revenge.

Richard Furstenau, a former state Senate candidate and a City Council member since 1999, was acquitted in May of misdemeanor battery and disorderly conduct charges after a short DuPage County bench trial. He had been charged with slapping an officer on the chest on Jan. 1, 2006, when he left a local restaurant and saw the officer directing the towing of vehicles from Chicago Avenue in downtown Naperville.

At the time, Furstenau was in the middle of a losing campaign for the Republican nomination for the Illinois Senate. The suit was filed in U.S. District Court.
