A vessel which is believed to have collided with a fishing boat off the coast of Shoreham on Sunday morning, causing the smaller boat to sink, has been identified.
The body of one fisherman has been found, two others are missing and a fourth fisherman was recovered alive.
He had been clinging to a buoy for more than five hours.
The man who died has been formally identified as 50 year old Traiam Dumitrache, a Romanian national from London.
Police say they are in touch with the owners of the scallop dredging boat, Vertrouwen.
The owners, MacDuff Shellfish Ltd, are co-operating with the operation.
The vessel left Shoreham around the same time of the incident at the weekend bound for Grimsby.
