Rialto, California, in San Bernardino County, has about 105,000 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 District Attorney files charges, a case in the Superior Court of California, County of San Bernardino. 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.

The FBI lists Rialto with an arrest reporting agency of its own, filed as Rialto Police Department. It reported 3,434 arrests for 2023, its latest complete year. 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 San Bernardino County Sheriff's Office is the county agency. It reported 10,411 arrests for 2022.
The FBI's agency list also places these agencies in San Bernardino County: California State University at San Bernardino, Chaffey College and San Bernardino Community College (campus police); the San Bernardino Unified School District, the Fontana Unified School District, the Victor Valley Union High School District, Union Pacific Railroad in San Bernardino County and one more (other); California Department of Forestry and Fire Protection at San Bernardino and Patton State Hospital (state agency); the Highway Patrol's Inland Division, the Highway Patrol's Inland Investigative Services Unit, the Highway Patrol's Barstow, Needles, Victorville, Rancho Cucamonga, San Bernardino, Arrowhead and Morongo Basin Area Offices and the Highway Patrol at Mountain Pass Port of Entry Commercial Vehicle Enforcement Facility (state police).
How Many Arrests Rialto Reports
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.
- Rialto: 3,434 for 2023, 5,519 for 2022, 4,658 for 2020 and 3,979 for 2019; 2021 is missing months.
Rialto's 3,434 arrests in 2023 were down 38 percent from 5,519 in 2022.
Across San Bernardino County, the seven agencies with all twelve months of 2025 on file reported 16,078 arrests between them.
Booking: Where People Arrested in Rialto Are Held
The county jail is where a person arrested in Rialto 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 4,570 people, down from about 5,510 in 2019. Its rated capacity in 2023, the last year with a capacity figure, was 7,556 beds, and it ran at 60 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 San Bernardino County Sheriff's Office at jimsnetil.shr.sbcounty.gov/bookingsearch.aspx (page title: County of San Bernardino Inmate Locator), phone (213) 894-2485, which answered when SearchSystems opened it on September 23, 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.
A person sentenced to prison serves the sentence in a facility of the California Department of Corrections and Rehabilitation, whose inmate locator is at cdcr.ca.gov/search.
How to Find Out About an Arrest in Rialto
An arrest in Rialto can be traced in three places, depending on where the case stands: the custody page of the San Bernardino County Sheriff's Office described above, for anyone booked into the county jail; the case index of the Superior Court of California, County of San Bernardino, which shows whether charges were filed and the next court date (the court records page SearchSystems verified is at sanbernardino.courts.ca.gov/online-services/case-information-documents); the District Attorney, which decides whether an arrest becomes a charge (its page is at da.sbcounty.gov, phone (909) 382-3800).
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 Rialto
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.
