This is the moment two women clashed over a youngster being noisy on a subway train in Thailand.

Footage shows a furious grandmother ranting at a female commuter who told her to look after her unruly grandson on the BTS Skytrain in Bangkok.

The child had reportedly been playing around and accidentally struck the woman, prompting her to complain.

However, the guardian reportedly flew into a tirade and said: 'He is a child! It's a child's nature. B***h! Second time already. Don't you see that I'm on a phone call?'

She was said to have hurled insults, mocking the woman's appearance and threatening to kick the woman off the train.

The pair later separated without the row escalating into a physical fight.
