Border guards did not allow Malashenko to leave Russia. Why - did not say

The situation around the Media Most remains tense and scandalous: after Gusinsky, the first deputy chairman of the board of directors of the holding, Igor Malashenko, was banned - he was forbidden to leave the country to the Economic Forum to Salzburg. The editor -in -chief of Echo of Moscow, Alexei Venediktov, said that the entire delegation of the "bridge" was already on the plane, "when the border guards entered, the motors were drowned out, and Malashenko was reported that he was temporarily not allowed to leave the country." At the same time, according to the head of the press service of Dmitry Ostalsky, the border guards did not explain why they did not release Malashenko (the story is all the more strange, that a few minutes earlier the same border guards, apparently, did not mind his departure - because Malashenko passed border control before landing?)
