Patrol Division Havre de GraceDepartmentsPolice DepartmentPatrol Division The Patrol Division is the primary function of the Havre de Grace Police Department. Officers assigned to patrol work permanent 12 hour shifts that cover 24 hours a day, seven days a week. While assigned to patrol, officers handle various calls for service to include assaults, domestic incidents, traffic collisions, robberies, and burglaries. When not handling a call for service, officers conduct traffic enforcement, patrol checks of businesses, and maintain a visible presence in our communities. Another very important aspect to the Patrol Division is the support the officers provide for the numerous special events that occur around the City of Havre de Grace annually. After working in the Patrol Division for at least a couple of years, officers are eligible to apply for other duty assignments within the agency as positions become available.
