RPF Constable Chetan Singh, opened fire from his official automatic gun inside the moving train after it crossed Palghar Station at around five in the morning
IUML members had raised anti-Hindu slogans such as 'Ambalathil Ketti Thooki' (We will hang you in the temple) and 'Pachakkittu Kathikkum' (We will burn you alive) during the protest march.
The action was taken after an FIR was filed based on a complaint that some people were pressing and offering money to needy people in the Modinagar area to convert them to Christianity.
The victim was watching games at a Muharram procession. Soon after, she was taken to a jute field by accused Ashfaq and Mumtaz where the two gangraped her.
