Mendota Arrest Records: Who Makes Arrests, Where People Are Booked and How to Get the Report

Who Makes Arrests in Mendota

The FBI lists Mendota with an arrest reporting agency of its own, filed as Mendota Police Department. It reported 82 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 La Salle County Sheriff's Office is the county agency. It reported 240 arrests for 2025.

The FBI's agency list also places one more agency in LaSalle County: Tri-County Drug Enforcement Narcotics Team (other).

How Many Arrests Mendota 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.

• Mendota: 82 for 2025, 82 for 2024 and 109 for 2023.

Through August 2026, Mendota reported 34 arrests, against 42 in the same months of 2025.

Across LaSalle County, the 13 agencies with all twelve months of 2025 on file reported 2,788 arrests between them.

Booking: Where People Arrested in Mendota Are Held

A person kept in custody after an arrest in Mendota 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 2019 the jail held about 110 people. Its rated capacity in 2019 was 306 beds, and it ran at 37 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 La Salle County Sheriff's Office at lasalleso.com/inmateSearch (page title: LaSalle Parish Sheriff's Office (LA)), 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 sentence of more than a year is served in state prison; the Illinois Department of Corrections lists its inmates at idoc.illinois.gov/offender/inmatesearch.html.

How to Find Out About an Arrest in Mendota

An arrest in Mendota can be traced in two places, depending on where the case stands: the custody page of the La Salle County Sheriff's Office described above, for anyone booked into the county jail; the State's Attorney, which decides whether an arrest becomes a charge (its page is at lasallecountyil.gov/m/directory/department?did=30, phone 815-434-8340).

Illinois is one of the states that lets anyone look up another person's statewide criminal history: conviction information is public under the Uniform Conviction Information Act, through the Illinois State Police. That record shows what agencies reported to the state, which is wider than one county's court index but can lag it.

Getting a Copy of an Arrest Record in Mendota

An arrest report belongs to the agency whose officer wrote it, and that agency releases it, not the court or the jail. Under the Illinois Freedom of Information Act the agency must answer within 5 business days, with one 5-day extension, and it may charge copying only after the first 50 pages.

• An arrest by the Mendota police: the police department's page SearchSystems verified at mendota.il.us/police (page title: Police | City of Mendota | Mendota IL), phone 815-539-9331, 607 Eighth Avenue Mendota, IL 61342, which answered when SearchSystems opened it on September 26, 2026.
• An arrest by the La Salle County Sheriff's Office: ask its records unit.
• A defendant who has been charged gets the report through the case: the State's Attorney, 815-434-8340, handles discovery for pending cases.
• Any county record that is not posted: the county records request page SearchSystems verified is at lasallecounty.com (page title: FOIA/Public Records).
• Your own statewide record: a name-based or fingerprint-based request to the Illinois State Police.
