A Hong Kong police officer has been arrested and suspended from duty after a video of him abusing his son went viral on social media on Wednesday. The 41-year-old was held on Friday on suspicion of “ill-treatment or neglect by those in charge of a child or young person” before he was released on bail, police’s public relations bureau said. “The police force places great importance on the discipline of its members. Any illegal behaviour found after the investigation will be severely punished,” a bureau statement said. The case has been handed over to the Hong Kong Island child abuse investigation unit. The original uploader of the YouTube clip said the video appeared to have been taken from a camera in the police officer’s house in South Horizons. Police said the incident took place in January.

The 15-minute video was later removed from YouTube, but it began circulating on WhatsApp and other social media sites.
