Man continuously calls a fellow passenger on the Downtown Line MRT train "f**k you."

Before SBS Transit employees separated the two customers, a guy was observed swearing at another man aboard the Downtown Line MRT train as it traveled from the Bugis station to the Rochor station.

Staff members of SBS Transit diffused a fight.

The man in yellow then pushed the man in grey to get off the train, and an SBS Transit employee came up to them at the stop to break up their argument.

When the man in grey started speaking to the staff, the man in yellow started yelling "F**k you" a lot and even dared the commuter to contact the police.

At the end of the video, a staff member wearing a black jacket and carrying a walkie talkie approached and conversed with the individual wearing gray.

When the train was moving from Bugis to Rochor, the man in grey could be heard ordering the personnel to look through the security film to find evidence that the man in yellow had reportedly "anyhow scolded people".
