The video clip, uploaded in social media and Youtube, showed the Class-VII girl and one of her neighbors of the same age, who were in love with each other, being beaten at Kunderchar Abdul Mannan Mallik Kandi High School ground in Kunderchar area.
Locals said the girl and the boy of Kunderchar allegedly eloped on February 6 but in vain as they were caught at the end of the village.
Later, they were taken to the house of former UP chairman Liakat Mallik at the village where they were beaten mercilessly overnight with their hands tied.
The following day, the victims were taken to the school ground where they were paraded in public and beaten by several people with shoes putting around their necks.
The perpetrators left the teenagers at the field with their hands tied. Later, their families rescued them.
Former UP chairman Liakat Mallik said since local administration seldom visits the area due to inaccessibility, he has to take up the responsibility of settling such matters.
Sub-inspector of Zanjira Police Station Sanjay Kumar Saha said actions would be taken against the accused if the victims file a complaint against them.
