The video features an unidentified woman on the tram screaming a racist and clearly xenophobic rant.
"What has this country come to?," she asks. "A load of black people and a load of f***ing Polish... none of you are f***ing English."
The most disturbing part may be that her comments are shouted past the ears of a small child, believed to be hers, seated in her lap for the entirety of her tantrum.
The woman's hateful tirade shocked the other passengers in the car. So much so that an older black woman interceded and asked that woman watch her language, especially in front of the child. That, however, only increased the tension and incited a loud and profanity laced argument.
The New Zealand Herald notes what happened next:
"Yeah, it's fine. I have got a little kid here. Have respect? I have a little boy here. F*** you. I dare you, I f***ing dare you," she shouted.
"Don't watch my language. Go back to where you come from, go back to f***ing Nicaragua or wherever you come from. Just f***ing go back.
"You ain't British, you're black. Where do you come from? 'No, someone's got to talk up for these lot."
Watch it unfold below (Warning for strong language):
According to the BBC (via the Herald) the British Transport Police arrested the 34 year old British woman for a "racially- aggravated offense:"
The incident occurred on the Croydon to Wimbledon Tramlink route, although police are yet to ascertain exactly where or when it happened. In the video the woman is told by another passenger to watch her language as there are children on board and to show respect to fellow passengers.
The British Transport Police went on to say they would "not tolerate racism in any form on the rail network".
