Foo Fighters rocker Dave Grohl publicly threw an unruly fan out of the band's London gig on Monday after he started a fight with a fellow concertgoer.

The hitmakers were performing at the iTunes Festival when Grohl spotted a man in the audience causing a scuffle.

So Grohl, with his microphone in hand, decided to take action and call out the perpetrator for instigating a problem.

According to NME.com, Grohl addressed the fan from the stage, "You don't f**king fight at my show you a**hole. Let me see him, who's fighting right now? It's that guy in the stripped shirt. Hey motherf**ker look at me, get the f**k out of my show right now."

Angry Grohl added, "I don't put up with that bulls**t - you people came here to have a good time and that guy can f**k off."
