Divers will check today if six missing mainland crew are trapped inside their sunken fishing boat off Po Toi Island. A Marine Department spokesman said a barge would tow the Luk Fung 28705 to shallow waters or to the shore. 'Then the Fire Services Department divers will go into the water and check whether the crew are still trapped inside the cabin,' the spokesman said. Six of the nine-man crew were asleep in the cabin when the vessel was in collision with the Panamanian tanker Dignity on Sunday night. The three others were picked up by another boat. The fishing boat is 25 metres underwater, three nautical miles west of Po Toi. Strong currents prevented divers reaching the boat on Tuesday, the spokesman said.
