Olympic gold medalist Caster Semenya has been lambasted on social media after posting a picture of a dying rat being "abused."

The video shows a rat caught in some kind of liquid. While it is struggling to move a person's hand can be seen flicking an elastic on the rat.

Caster made light of the disturbing video and added a caption that alluded to the rat "deserving" the treatment.
