The 4-minute clip from last year shows a woman repeatedly beating a toddler. She was jailed for 18 months for that.
The video, which runs for about 4 minutes, was posted last Friday on the social networking site and has had more than 22,000 shares. It shows the child lying prone on a mattress and crying as the woman pinches, kicks and beats it with a pillow repeatedly.
The beating continues even as the child seems to have stopped crying.
Another woman, presumably the one shooting the video, keeps telling the abuser, whom she calls Ira, to stop the beating.
“Why are you showing your anger to the child? Do you want to kill her?” says the other woman. The clip was however removed earlier today.
In his Twitter posting, Khairy said he had informed Home Minister Hishammuddin Hussein about the video.
Khairy said the abuse was unforgivable and that he felt physically sick watching the video.
“The one who took the video is equally cruel,” he tweeted. “She did nothing to save the toddler. Conspiring to commit a crime.”
In further tweets, Khairy revealed that he was informed by Hishammuddin that it was an old case and that the police had taken action against the woman.
He said that the woman was charged and jailed for 18 months in Petaling Jaya last year.
