Auxiliary Police

The Cambridge Auxiliary Police Department has been serving the city of Cambridge since 1941.  Originally created as a civil defense measure, the Auxiliary consists of volunteers who assist the Cambridge Police Department with traffic and crowd control at parades, festivals, road races, and other city events.  The Auxiliary also conducts vehicle and foot patrols during holidays and other times as needed. 

The Auxiliary currently meets on the first and third Wednesday of every month at 7 PM.  Meetings are held at the Public Safety building at 125 6th Street in either the Community Room on the 1st Floor or the 4th Floor Academy Classroom.
