A Saratoga Springs man sued the City of Troy and three police officers on Monday, alleging that he was the victim of unjustified brutality by officers who used a Taser and pepper spray on him during an arrest at St. Mary’s Hospital. The complaint, filed by attorney Terence Kindlon on behalf of John M. Larkins, alleges assault, battery, false arrest, excessive force and malicious prosecution for the Aug. 27, 2011, incident.
