A case of culpable homicide has been registered in Mumbai against the owner of Varaprada tugboat that sank in the Arabian Sea during last month's cyclone Tauktae, in which 11 persons were killed, an official said on Friday.

Barge P305 and Varaprada - both support vessels working for the state-run ONGC's offshore oilfields near Mumbai – had borne the brunt of cyclone Tauktae, which made landfall on Gujarat coast on May 17.
