The two environmental quality control specialists from Kaunas, Ausra Bruziene and Ausra Kriceniene, are suspected of failure to carry out their duties. Suspicions against them were brought on Friday.
"Both specialists refuse to cooperate with law enforcement institutions as part of the pre-trial investigation, refuse to provide evidence and explain the incident's circumstances. They have signed obligations to stay at a designated place," prosecutors said.
