The DS did not act, despite a notification in advance that the spill gates of Iranamadu tank would be opened on December 22 following heavy rains.
When the ensuing flooding hit, the DS and other officials had been attending the annual get-together of the Kandawala divisional secretariat.
Irrigation engineer Sudakaran said the DS, military and disaster management officials had all been informed on December 06 about the imminent opening of the spill gates.
The flooding affected Dharmapuram, Murusumudai, Sivapuram, Udasalpuram and other areas of Paranthan.
Attempts to contact the DS for a comment failed.
