The incident took place on June 13 and the complaint was also filed on the same day at Gadi Malhera police station, Additional Superintendent of Police (ASP), Neeraj Pandey said.
According to the complaint lodged by the girl's father, the problem began when his daughter was fetching water from a village hand pump and her shadow fell on muscle-man Puran Yadav (belonging to a higher caste) when he happened to pass from there, the ASP said.
Yadav's family also prevented the victim from going to police station, but they somehow managed to reach there.
A case under sections 323, 341, 506 of the IPC has been registered against the accused and further investigation is underway.
In several remote pockets of India, where untouchability is still prevalent, people from the lower caste are forbidden to come in contact with those belonging to the higher rung so much so that they can't share their food, cook for them or even look them in the eye. It is even forbidden for their shadow to fall on higher caste people, who consider it as defiling or polluting.
