Lassen County, California, has about 28,000 residents (2024 Census Bureau estimate), and arrests there are reported to the FBI by the Lassen County Sheriff's Office, one city agency and three 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 District Attorney files charges, a case in the Superior Court of California, County of Lassen. 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.

One city in Lassen County reports its arrests to the FBI separately:
- Susanville, 12,359 residents: 317 arrests reported for 2025.

How Many Arrests Each Agency Reports in Lassen County
The FBI publishes every agency's monthly arrest counts 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.
- Susanville: 317 for 2025, 327 for 2024, 187 for 2023, 208 for 2022, 451 for 2020 and 455 for 2019; 2021 is missing months.

Booking: Where People Arrested in Lassen County Are Held
The county jail is where a person arrested in Lassen County and kept in custody ends up, whichever agency made the arrest, though a city department may hold someone in its own cells first and a person cited and released at the scene is never booked. The jail's record of each person held, with the charges, is a public record of the arrest, and once the person is released or sentenced the record continues in the court file.
On an average day in 2025 the jail held about 76 people, down from about 100 in 2019. Its rated capacity in 2019, the last year with a capacity figure, was 210 beds, and it ran at 50 percent of it that year. The figures are from the Vera Institute of Justice's Incarceration Trends data.
A sentence of more than a year is served in state prison; the California Department of Corrections and Rehabilitation lists its inmates at cdcr.ca.gov/search.
How to Find Out About an Arrest in Lassen County
For Lassen County the place to look is the case index of the Superior Court of California, County of Lassen, which shows whether charges were filed and the next court date (the court records page SearchSystems verified is at lassen.courts.ca.gov, phone (530) 251-8205).
California does not let the public search another person's statewide criminal history. The record kept by the California Department of Justice 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.
Getting a Copy of an Arrest Record in Lassen County
The report of an arrest is released by the agency that made it; the jail and the court hold their own records of the same event, but not the report. Under the California Public Records Act the agency must answer within 10 days, with up to 14 more days in unusual circumstances, and it may charge the direct cost of copying only, not staff time.
