This was reported by the press service of the Moscow Interregional Investigation Department for Transport of the Investigative Committee of Russia.

"According to preliminary data, on December 23, a man born in 1995 was not allowed on board the plane en route Moscow - Kirov, due to the fact that he was in a state of alcoholic intoxication," the press service said.

The UK said that the man, disagreeing with this decision, "hit the flight attendant in the head, causing bodily harm."

A pre-investigation check was organized on the fact of violation of public order on board the aircraft.

Earlier, the Investigative Committee opened a criminal case on the fact of a fight on board the plane between two passengers on the Sochi-Moscow flight.
