Cecil the Lion | Killed by Dentist Walter Palmer Track

The American dentist who sparked global outrage when he killed an endangered black-maned lion in 2015 has been sighted hunting again.

Walter Palmer, 60, from Minnesota, is reported to have made his return to the blood sport by travelling to Mongolia to slaughter the Altai argali -the largest wild sheep in the world.

In an image which has recently emerged on social media, the dentist, whose face is edited out of view, is seen showing off the dead animal next to another trophy hunter, The Mirror reported.

The scenes come nearly five years after the dentist sparked protests across the world for killing Cecil the Lion in Zimbabwe with a bow and arrow.

Palmer is believed to have paid up to £80,000 to kill the wild animal in Mongolia last year, according The Mirror.

Following the revelation Dr Teresa, wildlife vice-president at Humane Society International told The Mirror: 'For trophy hunters to travel to Mongolia to kill a beautiful and ­endangered ram is an absolute outrage.

'The argali ram is a species in danger of extinction, so the idea that these animals can be killed for pleasure is abhorrent.

'The killing of Cecil the lion five years ago caused international shock. But clearly the killing for kicks continues.'

During his trip to Mongolia, Palmer and his friend Brent Sinclair are believed to have climbed the hills in the Altai region and come as close as 20 yards to sheep.

Following the trip in 2019, Mr Sinclair shared a post on Facebook which read: 'Another great adventure has come and gone, one to be put in the memory book for sure. Just back from Mongolia, and it's almost like it was only a dream.
