Three people on Tuesday filed a criminal complaint against Tokyo Electric Power Co. and 32 of its current and former executives with the Fukushima Prefectural Police, arguing they neglected to take measures to prevent radioactive water at the crippled Fukushima No. 1 nuclear plant from flowing into the ocean.

Among the three is Ruiko Muto, who heads a group of some 14,000 people who have filed a criminal complaint with prosecutors against the utility, its executives and government officials, arguing they should be held liable for failing to prevent the Fukushima nuclear disaster.

In the latest complaint, the three said the failure of Tepco and its executives, including current President Naomi Hirose, to take appropriate steps has caused the daily outflow of up to 400 tons of radioactive water into the Pacific.
