Passengers at Victoria station were left "gobsmacked" after a man urinated out of a Tube train onto a platform full of passengers on the morning commute.
Onlooker Cat Davies said London had "hit a new low" after a "jet of liquid" hit her feet as she got to the busy station at around 9.54am on Tuesday (September 21).
British Transport Police told filmmaker Ms Davies the incident was "wholly unacceptable" and should be reported.
Others naturally reacted to the news with disgust, with one Twitter user saying it was "gross".
Anthony Hill added: "With any luck it'll be on CCTV, the platforms there have enough cameras."
Another was quite simply lost for words, commenting: "Wow".
It is not the first time an incident where humans relieving themselves have caused a stink.
