Officials said two men, including the person who captured the crime on video and later shared it on social media, have been arrested.

The viral video showed the woman pleading to the accused and asking them to consider the “sanctity” of the Ganga, which she addressed as “mother”.

Local villagers alleged that when the woman reached the concerned police station to lodge her complaint against the culprits, the policemen refused to register FIR.

Police took the case seriously only when they found the viral video on social media, and superintendent of police (rural) Anand Kumar took up the case to monitor it.

Police commented that woman was dragged out of the river by a man named Shivpujan Mahto, a driver, and took turns to rape her along with others.

Police have arrested the accused and also rescued a minor girl whom Mahto had lured into accompanying him.
