As reported by Censor.NET, this was announced by Prosecutor General Yurii Lutsenko on air of ZIK.
Lutsenko said an expertise found that the fire in Hrybovychi dump site near Lviv last summer was caused not by an arson, but by failure to comply with safety requirements.
"So the issue of negligence by officials of the Lviv City Council that caused the situation is on the agenda.... It is aggravated with the fact of three deaths. The families have the right to ask who of the Lviv City Council is responsible for that. At the moment, a pretrial investigation by the regional prosecutor's office is looking for the "who." I do not rule out it might be the mayor, his deputies, and other officials," Lutsenko said.
The prosecutor general added that if an indictment is served to Sadovyi, he might face dismissal and criminal prosecution.
Earlier, a large-scale fire broke out at Hrybovytske dump site in the vicinity of Lviv May 30. A waste pile slid and swamped several firefighters after the fire was extinguished and they were gathering the equipment and examining the site. Bodies of three killed firefighters were later found in the slide. Criminal proceedings into the tragedy were initiated.
