Complete a SAPS 55(A) form at your nearest police station
The SAPS 55(A) is the official missing person report. It also gives the police permission to distribute the missing person's photograph and information publicly.
Take a recent, good-quality photograph with you. Before you leave the station, make sure you have the case number and the name and contact details of the investigating officer.
Do not let anyone tell you to wait 24 hours. No such waiting period exists in law.
