The appearance of the drone caused a delay to the game, as well as unnerving some Qarabag supporters.
Officials paused the game when the drone appeared over the pitch and sent both teams to the dressing rooms. Fans of the home team stormed the pitch, in spite of security which struggled to contain the Azerbaijani supporters.
Shortly after the match, the separatist group "First Armenian Front /FAF ultras/" published an image on Facebook explaining the origins of the action. According to the group, "the action was led by the young people of Belgium thanks to Spartak J".
Minister of Sport Dan Kersch presented his apologies in the name of the government for this provocation. Although the match was interrupted, play resumed after almost 20 minutes.
Police also reported that a number of cars had been broken into during the match, in a car park near the stadium.
