Montgomery County, Maryland, has about 1.1 million residents (2024 Census Bureau estimate), and arrests there are reported to the FBI by the Montgomery County Sheriff's Office, one other county agency, four city agencies and two campus, state or other agencies. An arrest leaves the same records whoever makes it: the arresting agency's report, the record of anyone held at the county jail, and, if the State's Attorney files charges, a case in the Circuit Court for Montgomery County. This guide says who keeps each one, what it costs and who may see it, with the arrest counts each agency reported.
This guide covers who makes arrests, how many arrests, booking and the jail, finding an arrest, copies, cities and common questions.

The Montgomery County Police Department also reports arrests to the FBI as another county agency of Montgomery County.

Booking: Where People Arrested in Montgomery County Are Held
A person kept in custody after an arrest in Montgomery County is held at the county jail, whichever agency made the arrest, apart from the short stay some city departments' own holding cells allow; a person cited and released at the scene is not booked at all. The jail's record of each person held, with the charges, is a public record of the arrest, and the court file takes over from there.
On an average day in 2024 the jail held about 920 people, up from about 750 in 2019. Its rated capacity in 2023, the last year with a capacity figure, was 1,163 beds, and it ran at 77 percent of it that year. The figures are from the Vera Institute of Justice's Incarceration Trends data.
SearchSystems opened and checked the custody page of the Montgomery County Sheriff's Office at mcsojail.countygovservices.com/Home/CurrentInmates (page title: Current Inmates | Montgomery County Sheriff's Office), which answered when SearchSystems opened it on September 28, 2026.
That page is the place to look for someone who was booked recently; a person cited and released at the scene, or held only a few hours by a city department, will not be on it.

Statewide, Maryland Judiciary Case Search is the free statewide case search of every Maryland court.
Maryland does not let the public search another person's statewide criminal history. The record kept by the Maryland Department of Public Safety and Correctional Services, Criminal Justice Information System goes to the person it belongs to and to employers and agencies the law authorizes; for everyone else the court's own case index is the public record of an arrest that led to a charge.
