He refused to wear a mask, shoots a gun and kills two people in Moscow.

The suspect, who was later arrested by security forces, pulled out his gun and began shooting those in attendance after being asked to set the mask and implement anticonvid protocols for closed facilities.

According to the Interfax news agency, the owner of the shooting opened fire when guards tried to force him outside the building.

Now an investigation has been launched, and if the perpetrators' author is found guilty he could risk the sentence forever.
