The statement said that the people at home and abroad are lifting their voice of demanding probe into the truth about the shell with flower-like white substance which was found out inside the torpedo propelling body produced by the authorities as overwhelming evidence of the "torpedo attack by the north."

It is the view of experts that in light of the size and shape of the discovered shell and white substance on it, the shellfish inhabited and grew there just after its birth and at least five months are needed for it to grow as big as that, the statement added.

It held that the "government" should no longer deceive the people over the "Cheonan" case but probe the truth about it though belatedly.

No matter how hard the authorities are working to cover up the truth behind the case, it would be clarified without fail, it stressed.
