The commentary recalled that the former chief of the guard office and administrator of Chongwadae who had been prosecuted for their involvement in the case of purchasing a housing lot in Naegok-dong were declared guilty at the trial on an appeal on Tuesday.

However, an investigation of Lee Myung Bak, the prime suspect in the case, has not yet been made as the prosecution studied his face, it said.

It recalled that in March last the organization filed a suit with the prosecution against Lee and his family on suspicion of their scandals.

The prosecution has not made any investigation into the case, far from summoning the chief culprit of the case for questioning, it noted, demanding a thorough-going investigation into the case.
