imageMadison Beer[1] cut her mid-day concert short after a gun scare erupted in the crowd beneath her -- which ended with the removal of a guy who's now banned from the premises.

It all went down Saturday evening at the BottleRock festival in Napa, CA -- where Madison was in  the middle of performing Radiohead's "Creep," when she abruptly stopped her crooning and ran over to the side stage in a panic after seeing something in the crowd.

In video of the incident, you can hear Madison frantically talking to her stage handlers, saying ... "What is going on? Yo, yo, everyone pay attention. What's going on?!" She then turns to the audience and tells them to back up, seemingly warning them of something happening on the ground.

While Madison Beer was performing, a man was thought to have pointed a gun at Madison after shouts of 'GUN!' was heard. Police reports confirm that there was no actual weapon involved. 🙏

People start to freak out and flee the scene ... reacting to what many perceived as a possible shooter situation. 

Further video shows police offers escorting the same guy away in handcuffs.
