A Hamburg police captain has been suspended after he was arrested following a domestic disturbance at his home last weekend. Capt. Christopher P. Monaco, 42, was charged with obstructing governmental administration, a misdemeanor, according to court records. The incident occurred about 11:27 p.m. May 11, according to a court complaint filed by Capt. James J. Koch. Monaco tried to prevent Koch from interviewing Monaco’s wife during a domestic disturbance, according to court records. “This action was performed by repeatedly yelling her name in an intimidating manner and stating ‘DO NOT TALK TO HIM,’ ” Koch stated in the complaint. Monaco also continually tried to give orders to members of the police department and “did physically engage these officers in an attempt to prevent them from performing their official function of investigating this domestic disturbance,” the complaint states. Police Chief Gregory Wickett said Monaco was placed on unpaid administrative suspension. He said the incident is still under investigation, and he declined to release a police report or provide more details. “In addition to a criminal matter, it’s a personnel matter, and it’s ongoing,” Wickett said. “Now it’s up to the chief what department discipline or charges will be brought against him,” Supervisor James M. Shaw said. Monaco was arraigned Wednesday before Town Justice Gerald P. Gorman, who released him on his own recognizance. Monaco joined the Hamburg Police Department in 1997.
