Laptop bag ****** in cabin - Safair - beware guys

I flew from Jhb to Dur on Fri 30 /09/2022 F. Upon exit I found that my laptop bag had been taken / ****** from the overhead compartment. It was clearly ****** and not taken in error because there was no other bag left behind. This is disgusting . What security measures does Safair have in place to apprehend these type of ********* on their flights ? The crew staff were not interested in helping and were rushing to turn around the flight. Complaint has been filed at lost baggage.
