An elderly man turned aggressive and challenged a bus driver and a transit security officer to a fight at Tampines interchange.
A video of the fight was sent in to citizen journalism website Stomp by a contributor.
The video, which has gone viral on the Internet, shows the old man aiming a kick at the bus driver while swinging his hands around like a martial artist.
Chaos erupted when he turned his attention to the transit security officer.
The old man flicked his shirt and challenged the security officer, prompting a fight as the latter defended himself.
The fight dragged on to the outer areas of the interchange before a bus captain managed to restrain the elderly man.
It is unclear when the incident took place though the video was uploaded in Jan 2013.
