Naz, in a statement, said, "I was completely shocked and was feeling sick about it. He casually sat there. I didn't know what to do with myself. Still feeling sick after reporting indecent sexual behaviour to @metpoliceuk on @TfL bus earlier!"
"I've never experienced anything like that. Women should be allowed to go about their business without this happening," she added.
Naz shared a YouTube video in which she discovered that around 90 per cent of people do not report any untoward incidents related to sexual misbehaviour.
In her statement, the British MP said that if such incidents go unreported, then it would add to the statistics.
She added: "It was really important for me to share the YouTube video."
"Always report it to ensure it is stamped out. Text What, Where and When to 61016 or call 101," Naz said on Twitter.
The British MP further stated that the man "had his bits hanging out" and was masturbating as she got off the bus.
Soon she reported it to the driver but the man had gone.
The London Metropolitan Police Department is currently investigating the incident. Further details in the matter are awaited.
