Attempted robbery start to finish: 23 seconds!

Armed robbers entered the premises of a well known jewellery store in Pretoria at 09h20. The sales assistant immediately triggers the smoke system. The first suspect gets to the back and is surprised by the smoke and the other suspect tells him to continue to the safe, but he turns and leaves as he cannot see the key holder nor the outside freedom, so he panics and jumps over the counter to get out with his accomplices just 23 seconds later!
