Marshals Service

Marshals Service, law enforcement agency under the U.S. Department of Justice, responsible to the deputy attorney general, and made up of executive officers of the federal courts. Established in 1789, the service has at present one marshal in each federal judicial district, and numerous deputy marshals. The service cooperates with state and local law enforcement forces.

Duties of marshals and deputy marshals include enforcing federal and district court orders; custody and transportation of federal prisoners; providing security for court witnesses, federal judges, jurors, and attorneys; preserving order on federal property; and disbursing certain appropriated funds. A marshal has the authority, with or without a warrant, to arrest violators of federal law. The service also supports activities of the Department of Justice during civil disturbances.
