The 24-year-old serial killer and rapist of Delhi who began his crime spree sometime in 2008 was first arrested last year for assaulting a minor boy in Begumpur in south Delhi. It is learnt that he abducted the boy near his house and fled after slitting his throat. He assumed the boy was dead. But the victim survived as police found him bleeding in a septic tank of an under-construction building.  Unfortunately the offender was let off in that case for lack of sufficient evidences against him. This year he was again arrested on July 16 for raping and murdering a six-year-old girl in Begumpur who had gone missing on July 14. On thorough interrogation by top officials of the Police, the serial killer and rapist has confessed to murdering more than 30 children after raping them; the toll might reach 40. Most of the offences committed by him have taken place in and around Delhi. His interrogators are even shocked to know about the enormity of his saga.
