The accused and the victim lived in the same area and used to go to each others' homes to study together. "On 8 November, one of the accused telephoned the girl and invited her to his home, saying he needed help with his studies. Once she arrived, he and his friends gang-raped her," Mr Sandbhor said. "The boys threatened the girl that they would upload the video on social media and raped her on several occasions thereafter. At the same time, they uploaded the video on WhatsApp," The boys were sent to a juvenile reform home, police said, adding that they were investigating further.
