21st Precinct (aka Twenty-First Precinct and Twenty First Precinct) was a police drama broadcast on CBS radio from July 7, 1953 to July 26, 1956. It was initially a summer replacement for My Friend Irma. The program was produced in cooperation with the Patrolmen's Benevolent Association of the City of New York and presented "adaptations from true criminal records in New York, slanted from the policeman's point of view." Other cast regulars were Ken Lynch (as Lt. Matt King), Harold Stone (as Sgt. Waters), Jack Orissa (as Sgt. Collins), and Santos Ortega (as Lt. Gorman).
