(1955) and Les Damon (1956).

Other cast regulars were Ken Lynch and Harold Stone.

The program's announcer began the program's opening each week:

21st Precinct. It's just lines on a map of the city of New York. Most of the 173,000 people wedged into the nine-tenths of a square mile between Fifth Avenue and the East River wouldn't know, if you asked them, that they lived or worked in the 21st. Whether they know it or not, the security of their persons, their homes, and their property is the job of the men of the 21st.

At that point the lead actor would complete the introduction:

The 21st Precinct. 160 patrolmen, 11 sergeants and four lieutenants of whom I'm the boss. My name is Kennelly. Frank Kennelly. I'm Captain in command of the 21st.

Art Hanna was the program's announcer. The series was produced by John Ives.
