The young Indian woman who is a viral dance influencer has finally posted a copy of the clip that she was trying to film for fans before a man attempted to grope her as she practised on the stairs.

Her now viral reaction taught the groper a painful lesson as he tries to molest the influencer while she is recording a social media clip.

Furious Mansi Suravase was creating the footage on the staircase of her apartment block in India when a neighbour gatecrashed the filming.

Mansi, wearing a traditional cropped saree top and an embroidered white skirt, flattens herself against the wall to let him pass.

But as he walks by, he reaches out to stroke her bare arm inappropriately before trying to walk off with a smug smirk.

Clearly angry, Mansi grabs his wrist and confronts him before dishing out a ringing slap to his cheek that echoes through the stairwell.

Obviously in pain he puts his hand to his face and staggers up the stairs mumbling: "Sorry, sorry, sorry."

Mansi said later: "I was randomly recording a Snap, and in my own building too, when this boy behaved in such a disgusting way."

She shared the clip with her 1.2 million Instagram followers on 26th April who instantly piled in to support her.

One named as 'namita_dubey' said: "I wish I could go back in time and do exactly this to the men who groped me."

And user 'divyasen' said: "These people think that they can do such cheap things and get away with it easily. So proud of what you did to him."

Then 'powar8708' wrote: "Well done Mansi."

And when Mansi, who regularly posts her modern take on traditional Indian dancing, confronted her groper's family they apparently refused to apologise.

She says they claim he has mental health issues and could not stop himself groping her.

But Mansi said: "So just because of that, he can do anything without excuse?"

After the upset she recorded the video anyway and is now shared it with her fans, showing herself dancing and singing about money, although pointing out that the notes that she was holding were purely for effect and were actually cheap fakes.
