The Criminal Complaint Unit assists the public in filing criminal complaints, both in person and in writing. Once a complaint is filed with the Unit, it is carefully evaluated to determine if charges should be filed or an investigation should begin. If it is appropriate, the complaint is then assigned to one of the investigative bureaus within the Nassau County District Attorney’s Office.


If you are disabled or otherwise unable to come to the Criminal Complaint Unit, please mail completed forms or call 516-571-3505 and other arrangements will be made so that your complaint can be reviewed.
