Delaware State Police

The Delaware State Police (DSP) is a division of the Delaware Department of Public Safety and Homeland Security and is responsible for traffic regulation and law enforcement across the US State of Delaware, especially in areas underserved by local police departments. The DSP is headquartered in the capital Dover, Delaware.

The Delaware State Police currently employs 723 full-time officers, which is 75 troopers for every 100,000 residents in 2019, the largest number of any state police force.

Currently, the DSP operates out of eight barracks known as "Troops", not including Headquarters. Each county has one troop that is shared between patrol (Uniformed) and detective (CIU) units. Delaware State Police investigate over 33,000 criminal complaints yearly.

In Kent and Sussex Counties, the Delaware State Police serve as the primary law-enforcement agency that are not incorporated into municipalities who have their own law enforcement agency.

In New Castle County, the Delaware State Police shares primary jurisdiction with the New Castle County Police. The 1974 jurisdictional agreement between DSP and NCCPD states the New Castle County Police investigates complaints in residences or commercial areas located on county roads or community streets. The Delaware State Police investigates complaints in residences or commercial areas located on state roads or interstate highways. However, in an emergency incident, the closest New Castle County Police officer or Delaware State Police trooper will respond no matter where the complaint originates from.
