Shocking footage showcases the moment a vile woman unleashed a verbal racist attack on a fellow train passenger - before proceeding to threaten the man with physical violence.
Police have confirmed an investigation has been launched into the incident after they received reports of a "racially aggravated public order offence", which took place on a train at approximately 11:30pm on July 16.
Snippets of the conflict have been uploaded to social media, where commenters have condemned the woman's actions.
The footage begins with the woman, who is dressed in a purple and white outfit, calling the unidentified man a "f****** Algerian c***", reports The Mirror.
She then proceeds with her torrent of abuse, hurling racial slurs and comments about the man's weight towards him on the West Ham underground train - before threatening to knock him out.
Another woman also appears to become involved in the incident, which is being filmed from further down the carriage.
The video then cuts to the first woman moving towards the camera and challenging the man who is recording the encounter.
She says: "Carry on recording me because I don't care - I'll f*** all of yous up."
The pair then continue arguing - before the woman threatens to stab the man in the face.
She says: "I'll stab you in the face. You don't understand, look - I've been shanked in the face."
The clip has been posted on a popular Facebook account, where more than 300 people have left comments.
One said: "What an absolute embarrassment."
Another added: "Hope she feels shame, name and shame that's what I would do."
Others also praised the man holding the camera for staying calm in the face of the aggression.
British Transport Police confirmed that the spat had been reported.
