The officials — who were not named — were also interrogated on the actions taken by them to evaluate the fitness of the works and projects completed by contractors.

The investigators also questioned the officials on the fate of the projects implemented to avoid the repetition of flood calamities after lessons learned from the 2009 flood.

The source however denied the interrogated employees included officials arrested following the previous flood.

The Control and Investigation Board continued separate investigations into the causes of the inundation of several areas in the city following the Jan. 26 downpour.
