Complaint Against Sheriff's Personnel 

The Lake County Sheriff’s Office has a strict policy of providing highly professional law enforcement services to the Lake County community. To achieve this goal, it is imperative that all complaints against members of the Lake County Sheriff’s Office be thoroughly investigated. The Sheriff and his command staff would like to know when services need improvement and thereby provide a means for residents to address grievances of misconduct by sworn or civilian personnel. 

Below are some frequently asked questions (FAQs) relative to the filing of a complaint and the Sheriff’s Office procedures for addressing grievances.

How do I file a complaint?

Complaints alleging misconduct against a sworn deputy sheriff must be accompanied by a notarized Affidavit, by a notary of the State of Illinois, as per the provisions of the Illinois Uniform Peace Officer’s Disciplinary Act, Chapter 50 ILCS 725/3.8.

Complaints alleging misconduct against civilian employees of the Sheriff's Office may mandate a notarized Affidavit, depending on the particulars of the misconduct, but is not required by state law.
