The New Castle Police Department is one of the oldest existing police departments in the nation. In 1672, Edmund Cantwell became the High Sheriff over the town and river territory that included New Castle.

Today the New Castle Police Department continues the legacy established by those fine officers who served with the Department since the 17th Century. That legacy is one of dedication to duty and service with honor through five centuries of ever changing times.

The New Castle Police Department exists to preserve life and property and to provide a safe environment for residents of New Castle and visitors to the beautiful and historic city. By all standards, thanks in a large part to the service provided by the police department, New Castle is a safe and peaceful community in which to reside or to visit.
