A man filmed himself killing his baby daughter on Facebook Live before taking his own life.
Police in Thailand said the man, 21, hanged his 11-month-old child in the seaside town of Phuket, uploading two clips to the social media site.
He had “paranoia” after his wife left him, a spokesman said.
People could access the videos online for roughly 24 hours, until they were taken down.
Just last week, Facebook was criticised after a posting of the fatal shooting of a man in Cleveland in Ohio, America, was visible for two hours before being taken down.
The company has since said it was reviewing how it monitored violent footage and other objectionable material.
A spokesman for Facebook said of the Thailand killings: “This is an appalling incident and our hearts go out to the family of the victim.
“There is absolutely no place for content of this kind on Facebook and it has now been removed.”
The harrowing footage showed Wuttisan Wongtalay tying a rope to his daughter’s neck before dropping her from the rooftop of a deserted building.
Wuttisan’s suicide was not broadcast but his lifeless body was found beside his daughter, according to the police officer in charge of the case Jullaus Suvannin.
“He was having paranoia about his wife leaving him and not loving him,” Suvannin said.
Thailand’s Ministry of Digital Economy said it contacted Facebook on Tuesday afternoon about removing the videos, after receiving a police request.
Ministry spokesman Somsak Khaosuwan said: “We contacted Facebook today and Facebook removed the videos.”
However, Khaosuwan said the government could take no action against the company, adding: “We will not be able to press charges against Facebook, because Facebook is the service provider and they acted according to their protocol when we sent our request. They cooperated very well.”
After the company faced a backlash for showing the video of the Cleveland killing, Chief Executive Mark Zuckerberg said Facebook would do all it could to prevent such content in the future.
