An Oklahoma Request for Investigation is a formal legal request by a person or organization to initiate an investigation into a particular matter. This request is typically made to a state or federal law enforcement agency, such as the Oklahoma State Bureau of Investigation (OSI). Depending on the circumstances, an Oklahoma Request for Investigation may also be made to a local police department, county sheriff's office, or other investigative agency. Types of Oklahoma Request for Investigation include criminal investigations, civil investigations, and public records requests. A criminal investigation is an inquiry into an alleged crime, such as a murder, theft, fraud, or assault. A civil investigation is an inquiry into a civil matter, such as a contract dispute, landlord-tenant dispute, or consumer complaint. A public records request is a request for access to government documents that are considered public information.
