Buffalo police Lt. Gregory Kwiatkowski, the subject of three separate cases involving allegations of improper conduct, has retired, authorities said Wednesday.
With his retirement, two internal affairs investigations are now considered closed because the Northeast District police supervisor is no longer an employee, but a federal lawsuit alleging his use of excessive force in arresting two teens remains.
Kwiatkowski, who has more than 20 years on the police force and qualified for a pension, had been on long-term paid suspension after he allegedly attacked a fellow officer last summer, police said.
At the time, he was already under departmental investigation in connection with a Lancaster bar brawl, police said.
Kwiatkowski allegedly grabbed an officer by the neck July 15 during a dispute in the briefing room of the Northeast District station. He was reportedly upset over officers requesting transfers out of his platoon.
Internal affairs investigators were also reviewing his alleged role in a fight May 7 on the patio at Page's Grill and Bar on Transit Road in Lancaster after the Buffalo Police Benevolent Association's annual awards dinner.
Three officers have already been disciplined by the department for their role in the incident in which one officer punched an off-duty Niagara Frontier Transportation Authority officer. The NFTA officer had questioned their rowdy behavior and told them that other bar patrons were taking cell phone photographs of them.
Through his attorney, Kwiatkowski had denied any involvement in that incident.
Also last spring, Kwiatkowski and another officer were accused of using excessive force in arresting two Buffalo teenagers, one of them the son of a Buffalo police officer, after a BB gun drive-by shooting in 2009.
In a lawsuit filed in U.S. District Court, Kwiatkowski and Officer Joseph Wendel were accused of assault, negligence and violating the civil rights of Jeffery E. Campbell II, the son of Police Officer Annette Parker, and Donald J. Silmon. Officer Raymond Krug was also named in the suit.
A check of federal court records Wednesday showed the case is still pending. A city attorney represents Kwiatkowski in that case.
In a 2008 incident, Officer Cariol Horne was fired following a department hearing for jumping on Kwiatkowski's back while he was attempting to make an arrest. Horne had unsuccessfully argued at the hearing that she believed Kwiatkowski was choking the person he was attempting to arrest.
Several years ago, Kwiatkowski received a mayoral merit award for good police work.
