In most cases, crimes must be reported to the police department or law enforcement agency that has jurisdiction over the city or county where the crime occurred. Crimes involving consumer fraud or the unlawful discharge of hazardous materials may be reported to the Orange County District Attorney's Office (OCDA) Consumer and Environmental Protection Unit. Complaints involving misconduct by public officials or voting law may be reported in writing to the OCDA's Special Prosecutions Unit. Report of misconduct on the part of law enforcement officers should be reported to the internal affairs or professional standards section of the law enforcement agency with which the officer is employed.
In the event of an emergency, dial 911. You will be connected with law enforcement personnel who will assist you with the emergency.
