an elephant's trunk - sparking anger on social media. He was filmed in a wildlife reservation drinking from a can of Tusker, a popular local beer, before giving the rest of it to the elephant. "Just a tusker with a tusked friend," he captioned one clip posted on Instagram, which was later deleted from his account after a backlash from Kenyans in the comments.

The BBC analysed the footage and was able to authenticate it as genuine. The landscape and a well-known bull elephant point to it being filmed at the Ol Jogi Conservancy in the central county of Laikipia. A member of the staff contacted by the BBC at the privately owned wildlife sanctuary was shocked by the behaviour - and said the videos would be passed on to "the relevant authorities". "This should never have happened. We're a conservation and we can't allow that to happen," the staffer, only identified as Frank, said.

"We don't even allow people to go near the elephants." The Kenya Wildlife Service (KWS) was also probing the incident, the agency's spokesperson Paul Udoto told the BBC. The man involved does not use his name on his social media accounts, which all have a variation of the phrase Skydive_Kenya. In another clip shared on Instagram last Tuesday, he is seen feeding two elephants with carrots and then saying: "We are on beer time." The Instagram videos attracted hundreds of critical comments - with some calling for the man's deportation - before the posts were pulled down. The elephant that was given the beer is big in size, with long tusks - one in particular is distinctive as it is damaged. From other images and videos posted online, it matches the description of Bupa, a friendly male at Ol Jogi whose photo is often shared by visitors.

Bupa was rescued from a mass elephant cull in Zimbabwe in 1989 and brought to the conservancy when he was eight years old. Ol Jogi says it is home to about 500 elephants and regards itself one of the pioneers in rehabilitating animal orphans and releasing them back to the wild. (BBC/Instagram)
