Professional Zimbabwean hunter Theo Bronkhorst told AFP Friday he did nothing wrong on the hunt that killed Cecil the lion, adding he was shocked to find the animal was wearing a tracking collar.

"I don't believe I failed in any duties at all, I was engaged by a client to do a hunt for him and we shot an old male lion that I believed was past his breeding age. I don't think that I've done anything wrong," Bronkhorst said in telephone interview.
