On Sunday night, an unidentified man set fire to passengers after pouring petrol on them when the train reached Korapuzha bridge near Elathur. Nine people suffered burn injuries and are undergoing treatment at various hospitals.
The bodies of a woman, an infant, and a man, who went missing from the train after the fire, were recovered from the tracks near the Elathur railway station, late on Sunday night. Police believe they fell off the train or attempted to get down after seeing the fire.
