"They abused and beat us repeatedly. I begged them to leave us but they continued to misbehave and called me names," the girl was quoted as saying by NDTV.
According to the news channel, the video shows the men slapping the girl and hitting the boy with a tree branch in that attack which lasted for over 10 minutes.
The entire incident was filmed by one of the attackers on his mobile phone and was circulated on the mobile messaging application WhatsApp.
They were abandoned after the attack and the couple rode back into town on their motorbike. The girl did not tell her family about the incident but her uncle saw the video on WhatsApp and reported the matter to the police.
NDTV said four men have been arrested for the assault.
The attacker as well as the girl are from the same village and one of them was in love with the girl, the channel quoted unnamed police sources saying.
