A criminal complaint was filed by 13,000 people nationwide Thursday against 33 senior officials of Tokyo Electric Power Co. and the government's now-defunct Nuclear Safety Commission over the meltdown disaster at Tepco's Fukushima No. 1 power plant that was triggered by the March 11, 2011 megaquake and tsunami.

In the complaint filed with prosecutors, the 13,000 demanded that the accused be investigated and charged with professional negligence resulting in death and injury.

The complaint was the second filed, following one made in June by 1,300 people mainly from Fukushima Prefecture.
