The incident reportedly took place during the shoot of a Holi celebration on the sets of a Hindi singing reality show where the girl is among the contestants.
Papon is currently one of the judges on Voice India Kids along with singers Shaan and Himmesh Reshammiya.
The singer took to his Facebook account and shared his reaction on the incident through a post.
Supreme Court lawyer, Runa Bhuyan filed a complaint against him under the Protection of Children from Sexual Offences (POCSO) Act.
"I have raised the concern before the commission as this is a grave concern regarding the safety and security of those kids who participate in reality shows. They are at the disposal of those TV channels. We don't know how these kids are treated inside the platform. I hope the commission gives a proper response and also hold a proper enquiry," Bhuyan told ANI.
