RPF constable Chetan Singh’s hatred towards a particular religious community—three of whom he had gunned down inside the Jaipur-Mumbai Superfast Express—was not a recent development. The charge sheet filed by the GRP in connection with the rampage reveals that he had a history with communal animosity. He had earlier detained a member of the community when he was posted in Ujjain and also behaved inappropriately.

Singh, a constable attached to the RPF, Mumbai division, had fired on ASI Tikaram Meena and three others, Qadarbhai Bhanpurwala, Saifuddin Sayyed and Saifuddin Sayyed, on the Jaipur-Mumbai Express on July 31. The charge sheet includes his service record as well. During his 14 years of service, Singh had three offences registered against him. Singh got the job after his father passed away while on duty in 2007.
