A video of a Malaysian man killing a caged monkey went viral on social media, causing public outrage.

The video, posted by a Twitter user Friday, shows the man asking the monkey to say “Baby Sayang,” a statement reportedly popularized by a Malaysian actor. The man then says if the monkey did not tell it, he will shoot it. A few seconds later, the man shoots the monkey at the count of three. The animal is then seen bleeding profusely.

The video has since gone viral with over 18,000 re-tweets with people calling the man in the video “cruel.”

“This is heartbreaking to watch. could be a case of human-wildlife conflict where the macaque have caused a disturbance & the person opts to killing it,” one person commented. “It’s very disturbing and not normal to have that kind of behavior,” wrote another.

“i'm so mad have yall found this demon yet?? why cover his f----- contact name omg I can't sleep in peace knowing this monster is still out on the loose,” a third person wrote. “He must be psychotic. Only those with psychological problems can kill an animal like that. This is how serial killers start off,” another tweeted.

People for the Ethical Treatment of Animals, an animal rights organization, thanked people for tagging them and bringing the incident to their notice and also asked the person who posted the video to give them more information.

The incident comes a few months after six men were arrested in Vietnam after they killed and ate an endangered monkey on Facebook live. Police said the accused, aged 35-39, bought the Vietnamese langur from a hunter for $49 and live streamed the incident.
