“Investigators of the central office have detained four more persons,” the message says.

As specified, among the detained are the owner of the mine, the chairman of the board of directors of the company "SDS-Ugol" Mikhail Fedyaev and the general director of "SDS-Ugol" Gennady Alekseev.

In addition, the investigators detained Anton Yakutov, technical director of SDS-Ugol, and Anatoly Lobanov, chief engineer of Listvyazhnaya Mine LLC.

Earlier, Gennady Alekseev said that he was ready to bear any punishment after the accident at the Listvyazhnaya mine in the Kemerovo region.

During a meeting on the coal industry, Russian President Vladimir Putin criticized the board of directors of SDS-Ugol for non-compliance with safety conditions at the company's Listvyazhnaya mine in the Kemerovo region.

The head of state said that, according to the investigation, the reason for the tragedy at the Listvyazhnaya mine in the Kemerovo Region was the lack of control by the management of the mine over the work carried out with increased gas pollution.

On November 25, an accident occurred at the Listvyazhnaya mine in Kuzbass, as a result of which 51 people died and dozens were injured.
