In the attempt, the boy sustained serious injuries in his private parts and started to bleed.
While the boy is undergoing treatment at the Hallet hospital in Kanpur, police said they were at their wits end to come to terms with the incident and decide under which sections of the IPC lodge a case.
Both the victim and the aggressor are minors, in this case and as a result lodging complaint has becoming difficult, SSP Kanpur Shalabh Mathur confirmed.
