Supposedly it is a common problem with lion and leopard attacks where the client shoots. This is a general comment only. However there have also been cases where the client has saved the person being mauled. I think if you can not see the person as in this case, the tracker underneath the leopard, and are unaware of their proximity to the attacking leopard, it is just an unfortunate accident. Accidents happen.

I hope Punki makes a speedy recovery.
