Binghamton Police Chief Joseph Zikuski will step down following over two months of paid administrative leave and an ongoing investigation, according to an announcement from Mayor Jared Kraham. Zikuski was placed on administrative leave after his girlfriend was involved in an altercation with two teenagers on July 18. “Yesterday, I accepted the resignation of Binghamton Police Chief Joseph T. Zikuski,” Kraham said in Tuesday’s press release. Assistant Chief John C. Ryan served as acting police chief following the suspension. He will continue to stay in the role while the city appoints a permanent police chief in accordance with New York state civil service law.
