Uma Mageswari then decided to make her own video of the man and posted it on Facebook. The video has been viewed over 5 million times in just two days.
Uma, in her post, says she confronted the man and reported him to the cops.
"Upon further investigation this chap was found to be in possession of similar videos though I am told they were rather obscene in nature of unsuspecting victims," she wrote on Facebook.
Uma also wrote that the man made several excuses for what he did and instead of an apology, said "his last feeble attempt of an apology was that 'I was like his sister'".
Uma wrote she highlighted the incident hoping it would act as a deterrent for any such incidents in future.
Her post gained people's attention and they praised her for speaking out against the man. The post has nearly 28,000 shares.
It is not clear from the Facebook post if the man, identified as Suraj by her, was arrested by the police. NDTV has reached out to Uma Mageswari for further details. Click for more trending news
