"The court decided to choose a preventive measure in the form of detention for two months, until January 25," TASS quoted a statement.
Earlier, the court sent under arrest the chief state inspector of the Belovsky territorial department of the Siberian department of Rostekhnadzor Vyacheslav Semykin in the case of an emergency at a mine in the Kemerovo region.
On November 25, an accident occurred at the Listvyazhnaya mine in Kuzbass, as a result of which 51 people died and dozens were injured.
According to preliminary data, the explosion of methane is believed to be the cause of the accident at the mine.
The Investigative Committee has already opened a case on the negligence of Rostekhnadzor employees.
Two criminal cases will be investigated in the central office of the UK.
