SINGAPORE - A woman who grilled passengers about their race on a train last week has had both her YouTube channel and employment as a property associate terminated.

In a post on Facebook on Tuesday (April 27), Knight Frank Singapore said the woman's conduct was brought to its attention earlier this week.

"One of Knight Frank's core values is to be a responsible business to people and the community."

"The company maintains zero tolerance for hate speech and racism that threatens the foundations on which Singapore is built," it said, adding that the woman has been terminated from the company.

The woman, who was a property agent with the company, has also been delisted from the Council for Estate Agencies' public register.

In a separate statement to The Straits Times on Wednesday, YouTube said the channel was removed due to violations of its harassment and cyber bullying policies.

"We have strict policies that prohibit harassment on YouTube, including content that maliciously insults someone based on their race, gender expression or sexual orientation," said the spokesman.

"We quickly remove content that violates these policies when flagged."

Based on its Transparency Report, YouTube removed more than 100,000 videos in Singapore between October and December last year.

The YouTube channel that was removed had a total of 29 video uploads, 28 of which alleged racism.

It was purportedly run by a woman who was caught in a video dated April 21 on an East-West Line MRT train questioning passengers about their ethnicity while purportedly taking videos of them.

In the video uploaded by Twitter user Ryan Kalmani, the woman, who was dressed in pink, can be heard claiming that she was from Hwa Chong, and questioning other commuters in the cabin about their education.

The YouTube channel and other personal details of the woman were dredged up after the incident went viral on Twitter.

The woman's face can be seen in some of the clips, which show her accusing several members of the public of being racist and harassing her.

In other clips, the members of the public appear to be unaware that she was taking a video.

The oldest clip on the channel dates back to December 2016, but the rest were uploaded between April 2019 and earlier this month.

A police spokesman confirmed that reports have been lodged in relation to the incident on the train last week and that a 57-year-old woman is currently assisting in investigations.
