Two men were seen tossing another man into a dumpster in a Housing and Development Board (HDB) estate.
Footage of the incident was uploaded online.
It showed two men picking up a third man dressed in a black t-shirt and putting him in a dumpster following a brief struggle.
The incident occurred beside a Sembcorp garbage truck.
The green dumpster was marked with what appeared to be the "AMKTC" abbreviation, which stands for "Ang Mo Kio Town Council".
The person filming the scene off-camera could be heard giggling towards the end of the video at the sight of the bizarre altercation.
It is unclear what sparked the altercation, but a separate video showed the man in the black t-shirt throwing a kick and punch at the man in the white top.
Commenters reacted with shock at the video.
On Instagram, some commenters joked that this is the result of not paying the conservancy fees.
