US dentist accused of killing Cecil the lion 'upset' as hunter becomes hunted

As Zimbabwe police say he faces poaching charges, Minnesota dentist Walter Palmer faces furious criticism on social media

Who shot Cecil? First it was thought that a mystery Spaniard had the blood of one of Africa's most famous lions on his hands. Then came a fresh twist. The Cecil slayer, Zimbabwean conservations said on Tuesday, was in fact a dentist from Minnesota.

American Walter Palmer was said to be "quite upset" as the hunter became hunted. Zimbabwean police warned that he faced poaching charges, while there was a furious backlash on social media, with Facebook users variously calling for him to be publicly shamed, have his teeth pulled out without anaesthetic or be hunted and killed.
