Woman caught pooping in front of passengers in a bus after getting desperate and having nowhere to go

This is the disgusting moment a woman 'squatted down and pooed on a bus' in front of horrified passengers. The woman appears to be crouched at the front of the bus with her trousers pulled down. Despite multiple commuters taking out their phones to record the sickening sight, the woman doesn't appear to be phased. In the background, passengers can be heard voicing their disgust as they watch the woman's actions. A caption alongside the video suggests the woman was desperate and only squatted in a public as 'a matter of urgency'. It has been reported that the woman was on a bus in Hong Kong at the time of the incident although the exact location is not clear.
