In the video, a group of tourists can be seen sitting aboard a boat while their tour guide sips water. Moments later, one of the tourists allegedly pushes the guide into the water.

Several people on the boat can be heard laughing as the tour guide falls into the water.

The video has triggered strong reactions on social media, with several users condemning the alleged behaviour and rejecting suggestions that the incident could be dismissed as a joke.

One social media user criticised the act, writing: “Very bad behaviour. If he do not know swimming he would have drowned. This is an act of murder. Sri Lankan government should arrest the culprit whoever he is, if Srilankan govt value their own citizens and ban the culprit life long to Srilanka.”

It remains unclear from the video what happened to the tour guide after he fell into the water
