The crafty crocodile has popped up for the second time in three days, 3km from his former haunt in Yuen Long creek, witnesses say. Officials from the Agriculture, Fisheries and Conservation Department could not confirm the most recent reported sighting by a sand barge skipper late on Monday afternoon. But they admitted the rogue reptile had surfaced late on Saturday in the same area. Their teams were last night out in boats trying to find the crocodile, the spokesman said. When told of the reappearance - after no sightings from November 21 to Saturday - Australian crocodile hunter John Lever, now back in Queensland, was not surprised. 'I suggested to the department before I left that if the weather got cold he would probably move downstream where the water is warmer near the sea,' Mr Lever said. His advice before he left Hong Kong on Sunday was to locate the crocodile then put two new traps nearby. But crocodiles lose their appetites if the air and water temperature dips below 24 degrees and may not eat for one to two months. The latest unconfirmed sighting came after mainland crocodile experts Li Minjian and He Zhenzhao returned home after a river tour with Mr Lever.
