Shop staff were disgusted after a desperate passer-by stopped to poo on a row of parked motorcycles.

Repulsed employees complained after they noticed the mess on the ground when they arrived for work in Xinzhuang District, Taiwan on October 30.

Security cameras showed a middle-aged man rushing to the concealed part of the parked motorbikes before pulling down his pants and squatting.

After spending two minutes going to the toilet, he then casually walked away and mingled with other commuters on their way to work that morning.

The store owner's friend, Jian-Syun Huang, said they have reported the incident to the police.

She said: "We reported the man for vandalism but we were told that the store wasn't really damaged so the man is not guilty of anything.

''I don't know how he's allowed to do this without punishment. I hope we still identify him so others can be aware too."
