Gaithersburg, Maryland, in Montgomery County, has about 71,000 residents (2024 Census Bureau estimate), and its arrests are reported to the FBI by an agency of its own. An arrest in the city 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 the agency reported.
This guide covers who makes arrests, how many arrests, booking and the jail, finding an arrest, copies and common questions.

Who Makes Arrests in Gaithersburg
The FBI lists Gaithersburg with an arrest reporting agency of its own, filed as Gaithersburg Police Department. It reported 926 arrests for 2025. A city is listed separately whether the officers are the city's own or the sheriff's under contract; the FBI's list does not say which.
Outside the city, the Montgomery County Sheriff's Office is the county agency. It reported 841 arrests for 2025.
The FBI's agency list also places these agencies in Montgomery County: the Montgomery County Maryland-National Capital Park Police (other); the Montgomery County State Police (state police).
How Many Arrests Gaithersburg Reports
Each agency reports its arrests to the FBI by month, and the FBI publishes them on the Crime Data Explorer. These are the full-year totals, all offenses, as the FBI held them on October 8, 2026; a year with months missing or not reported is left out.
- Gaithersburg: 926 for 2025, 857 for 2024, 899 for 2023 and 803 for 2022.
Gaithersburg's 926 arrests in 2025 were up 8.1 percent from 857 in 2024.

Booking: Where People Arrested in Gaithersburg Are Held
A person kept in custody after an arrest in Gaithersburg 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.
