Travi$ Scott was arrested at Lollapalooza over the weekend after he encouraged the crowd to storm the stage. Watch footage of the incident below.
The rapper's set lasted just five minutes - during which he encourage fans to climb over the barriers and move closer to the stage, telling security: "Everyone in a green shirt get the fuck back."
Scott then began chanting, "We want rage" as the crowd followed his instructions and began climbing over the barrier. He added, "Middle finger up to security now."

Shortly afterwards, the music was cut off by the event organisers, and Scott attempted to "start over", telling fans to get down off and away from the stage. He wasn't quite as persuasive this time though, and the set was shut down.
As abc7 Chicago reports, Scott was subsequently arrested and charged with disorderly conduct. The Office Of Emergency Management issued a statement saying, "The performer played one song and then began telling fans to come over the barricades. Due to the security's quick response, the situation was remedied immediately and no fans were injured. The performer fled the scene and was taken into custody a short while later."
Meanwhile, the entire festival was briefly evacuated yesterday (2 August) due to a thunderstorm warning.
