A woman has been caught defecating on a Melbourne bus to the disgust of fellow passengers.
The disturbing incident was recorded on a mobile phone by a passenger.
People can be heard yelling "no, no, no, oh my gosh" as the groaning woman commits the indecent act in the middle of the bus.
She can be seen pulling down her pants and relieving herself on at seat.
The woman, wearing a grey beanie, a black hoodie and purple pants, is heard mumbling inaudibly on the footage after she finished making her mess.
