There was no more sitting space for passengers so some of them had to stand.

The train moved and everyone was looking forward to arriving at their destination safely.

A man, who was standing along with others, was however caught pleasurising himself by poking his erected prick against a woman bum.

The man, described as “pervert”, is seen standing next to the woman on the train in the disturbing pose, although the victim does not appear to notice as she continues to chat to a friend.

Several people witnessed the incident on the tube in East China’s Shanghai Municipality, but nobody called the man out on his disgusting behaviour.

The video was uploaded to Chinese social media and has been viewed more than 3.3 million times.
