In a clip that QX posted on Instagram, he stops singing and starts screaming from the stage:
Hello! Let my mom be!
According to the newspaper, he is said to have screamed at a guard who tried to escort his mother out of the area because she had an umbrella with her during the rainy performance.
Omar Rudberg says in the clip to his colleagues to stop the music and then continues to scream at the guard.
What the hell are you doing! This guard is attacking my mom, please take her. Let my mom be. What the hell are you doing? Shut up! Shut up! You don't touch my mom like that.
A few minutes later, he says to the audience that it's time to change the mood and thanks them for being there despite the rain and then continues the concert.
