I do not have the resources to run around courts for years. I want justice delivered right here. Only then will I take my son’s body.”He said a video of the assault is on social media and all those gathered at the hospital have seen it.The police said Ketan belonged to a Scheduled Caste community and was in a relationship with the minor daughter of Yashveer Singh.
