Indonesia's chief prosecutor has indicated that former President Suharto could be named as a suspect in the ongoing investigation into alleged corruption during his three decades in power.

The attorney-general, Andi Muhammad Ghalib, said the move, one step before a formal charge, could be taken based on evidence given by officials suspected of corruption.

Mr Suharto was questioned two weeks ago as part of a second investigation ordered by his successor, BJ Habibie.

A first inquiry had exonerated him.

Mr Suharto denies any wrongdoing.
