A West Bengal native was found dead in mysterious circumstances on the Thiruvananthapurambound Guwahati Express on Friday evening.
The deceased has been identified as 20-year-old Orao Dipak.
The body was found near the bathroom of the general compartment of the train which reached Ernakulam Town Station at 5.55 pm.
“The initial reports indicate poisoning as the reason for the death,” said the Railway police. They ruled out any case of physical assault as no external injury was found on the body.
According to the railway police, the person had died a few hours prior to the registration of the incident at the railway station. Railway police Ernakulam SI P Vinod said the passengers realised that the man lying on the floor was dead only after crossing the Kerala border, when a passenger brought their attention to it.
