A Thai man filmed himself killing his baby daughter on Facebook Live, before taking his own life, Thai police say.
The 21-year-old hanged his daughter, and then himself, at a deserted hotel in Phuket on Monday, reportedly after an argument with his wife.
A copy of the video was still available on Facebook on Tuesday afternoon.
Earlier this month, Facebook pledged to review its processes after footage of an American killing a man in Cleveland stayed online for hours.
Relatives of the Thai man, who has not been named, saw the distressing footage and alerted the police – but the authorities arrived too late to save the man and his daughter.
The footage shows the man tying a knot around his daughter’s neck, before dropping her from a rooftop. He then retrieves the body.
Social media anger
The Facebook Live post was widely reported by Thai media, and went viral on social media, BBC Thai editor Nopporn Wong-Anan reports.
Thai social media users reacted with anger, while offering condolences to the family of the girl, our correspondent says.
Devastated relatives of the child, including the mother, picked up the body of the girl and her father from hospital on Tuesday.
There was no immediate comment from Facebook, where representatives are looking into details of the case.
Following the US killing, Facebook said it was “constantly exploring ways that new technologies can help us make sure Facebook is a safe environment”.
“We prioritise reports with serious safety implications for our community, and are working on making that review process go even faster,” blogged one of its executives last week.
