After autopsy of bodies of the four fishermen who reportedly died by drowning after their boat was damaged by the Sri Lankan Navy, the bodies were first taken to Pudukkottai district in the afternoon and then to Ramanathapuram. Despite the order of Tamil Nadu Government to conduct re-postmortem and to videograph it at the Ramanathapuram District Government Hospital, the bereaved families consented to receive bodies, said sources.
