Contact Investigating Officer

Direct Answer: How to Report This Crime or Open a Case

To contact your investigating officer, you must first have an open case docket registered with the South African Police Service (SAPS) and an assigned CAS (Crime Administration System) number. Once your case is logged at a police station and referred to the Detective Branch, an investigating officer (IO) is assigned to handle your file.

You can contact your assigned investigating officer by calling the direct number provided in your official SAPS confirmation SMS, phoning the station’s detective branch directly, or visiting the police station where you logged the docket during office hours.

Emergency Notice: If you are currently in immediate danger, a crime is actively taking place, or a suspect is still on the scene, call 10111 immediately. Do not wait or attempt to contact an investigating officer for urgent, active emergency response.

If you have not yet logged a docket or need general context on starting the process, read our detailed guide on How to Report a Crime in South Africa.

When to Call 10111 vs Visit a Police Station

Knowing whether to call an emergency line or walk into a police station ensures you get the right assistance at the right time. For a direct comparison of these options, see our guide on Call 10111 or Go to Police Station.

• Call 10111: Use nationwide emergency police numbers when a crime is actively occurring, suspect vehicles or individuals are fleeing, or lives and property face imminent danger. 10111 call centers route urgent requests directly to active patrol units in the area.
• Visit a Police Station: You must physically go to your nearest police station to formally open a case, write and sign an official statement under oath, and receive a CAS number. Initial case dockets and investigating officer assignments cannot be requested or established solely over an emergency phone call.

What Information and Documents to Prepare

Having your paperwork and details organized before reaching out to SAPS helps officers process your docket quickly and gives your detective a stronger foundation for investigation.

Documents or details to prepare

• Identity Documentation: Original South African Green Barcoded ID Book, Smart ID Card, or a valid Passport/Permit for foreign nationals.
• Written Chronology of Events: A written timeline noting exact dates, estimated times, physical locations, and step-by-step details of the incident.
• Witness Contact Information: Full names, cell phone numbers, and addresses of anyone who observed the incident or has relevant information.
• Physical & Digital Evidence: Photos of property damage or injuries, CCTV footage saved onto a USB flash drive, serial numbers of stolen items, proof of ownership, or bank statements in fraud matters.
• Existing CAS Number: If you are following up on a previously reported matter, keep your original SAPS SMS or paper acknowledgment receipt ready.

Requirements

While SAPS officers are legally mandated to assist you even if you lack immediate documentation, presenting clear evidence and identification accelerates docket creation and reduces delays when your case is passed to the detective branch.

What Happens After You Report the Crime

When you log a crime, your complaint moves through a structured administrative process before reaching a detective:

1. Statement Taking: A police officer at the Community Service Centre (CSC) records your statement and asks you to sign an affidavit certifying its truthfulness.
2. CAS System Entry: The officer registers your report into the SAPS Crime Administration System (CAS), generating a unique case number.
3. Docket Routing: The physical and electronic docket is forwarded to the station’s Detective Branch Commander for review.
4. Officer Assignment: The branch commander assigns an investigating officer based on the nature of the crime (e.g., general theft, commercial crime, or violent crime).
5. SMS Notification: SAPS issues an automated SMS to your registered mobile number containing your official CAS number, the investigating officer’s name, and contact details.

CAS Number, Detective Follow-Up and Case Progress

Your CAS number is the primary key for all communications regarding your case. A standard CAS number uses the format CAS 123/08/2026 (representing Case Number / Month / Year).

To conduct a successful SAPS case follow up and reach your investigating officer, follow these steps:

1. Check Your Automated SMS: Review the initial text message sent by SAPS after case registration. It displays your assigned detective’s full name and contact number.
2. Call the Station Detective Branch: If you did not receive an SMS or lost the text, find the specific police station contact number and request to speak directly with the Detective Branch. Provide your CAS number to the detective on duty to look up your file.
3. Visit the Detective Branch in Person: If you cannot reach the branch by phone, visit the station’s detective offices during standard operating hours (07:30 to 16:00, Monday to Friday). Request to see your assigned investigating officer or the detective commander on duty.
4. Provide Updates & Keep Records: Use your meetings or calls to hand over any newly gathered evidence, request docket status updates (such as whether suspects have been interviewed), and note down the officer’s direct landline or work contact for future check-ins.
