SINGAPORE - The Ministry of Social and Family Development (MSF) is "looking into" an alleged case of domestic abuse after a video of the incident went viral on Monday (July 20) night.

The Facebook clip, uploaded by user ApohTecky Numero at 7.42pm, shows the frail-looking woman sweeping the corridor outside a HDB flat at Lower Delta Road under the watchful gaze of two other women.

Towards the end of the video, one of the women - apparently the elderly woman's daughter - is seen delivering a hard slap to the left side of her face.

As the elderly woman attempted to steady herself, she received another slap on the other side of her face.

The video has since garnered more than 320,000 views in less than six hours.

It also prompted a swift response from the MSF, which posted a statement at 10.11pm on its Facebook page.

"Some of you have shared a video showing an elderly woman being hit by a younger lady. We are looking into it. Please be assured that the elderly woman's safety is our priority," it said.

In an update posted close to midnight, ApohTecky Numero said the elderly woman was taken to hospital with a bandaged head. Police officers were also at the scene and took the daughter into custody, purportedly to assist in investigations.

Minister for Social and Family Development Tan Chuan-Jin mentioned the incident in a Facebook post early Tuesday morning.

"Whatever the context and reasons, I can't see how this is justifiable. Hitting an old lady like this?! We will follow up and make sure that the elderly lady is protected," wrote Mr Tan.

MP for Lower Delta, Dr Lily Neo, said she has requested her grassroots volunteers "to investigate the case immediately".
