Upsetting footage of a tiger being poked by a red hot poker has sparked outrage after it was posted on Facebook by a horrified tourist.
The clip, which shows members of staff at a zoo in Thailand jabbing the animal to elicit roars, has gone viral.
In the video, holidaymakers pose next to the big cat as it is poked in the face.
Edwin Wiek uploaded the footage to Facebook with the caption: "Today witnessed the ugliness of tourism and wildlife in Pattaya.
"This tiger gets poked all day, hundreds of times a day so it will roar for the picture with tourists.
"Time for a change of laws. Sharing this in advance of Thai National wildlife day on December 26th."
