The NCP on Thursday demanded registration of a culpable homicide case against the ONGC in connection with the barge tragedy caused off the Mumbai coast when cyclone Tauktae brushed past the city.

As many as 37 personnel onboard an accommodation barge, 'P305', died, while 38 are still missing after the vessel, contracted to state-run oil and gas producer ONGC, sank in the Arabian Sea on Monday after getting caught in the powerful storm.
