During his performance, he invited fans up on to the stage while he played. But one was left red-faced when he attempted to take a selfie with Morello.
As can be seen in the video footage below, Morello was having none of it and grabbed the phone and threw it into the main crowd.
Morello later reacted to the moment on Twitter, saying: “Put a phone in my face onstage and I’ll throw it. #LiveInTheMoment. Great fun today at the 101WKQX show. #SweetHomeChicago.”
The guitarist later received some flak on Twitter about the incident, to which Morello responded: "When you invite guests to your stage and clearly tell them, ‘If you stick a cell phone in my face I will throw it’ and then their uncontrollable entitled selfie urges overcome their sense of reason, they get their f*ckin phones thrown. Simple.”
He later added the fan got his phone back.
Last month, Judas Priest frontman Rob Halford hit the headlines when he booted the phone from the hands on a front row fan during their set at the Rosemont Theatre in Illinois.
He later explained: “The facts are we love our fans and you can film us all you like and watch our show on your phone rather than in the flesh.
“However, if you physically interfere with the Metal God’s performance, you now know what will happen.”
Morello and Halford join a growing list of musicians who have reacted to fans with phones at concerts in recent years, including A Perfect Circle, Green Day, Slipknot's Corey Taylor, Disturbed and Peter Frampton.
