He and other fellow fishermen decided to bring it home with them.  “It's large and heavy so we decided to stop fishing and just carry it home," said Binh. “There are burn marks on the piece.” Local officials said they are investigating the case, adding that the piece is around 1.5 by 3.2 meters.  By Ngoc Minh, Thanh Nien News
