The incident happened during a performance in San Bernardino, California.
Marilyn Manson has released a statement, after he pointed a fake assault rifle at his audience during a performance in San Bernardino.
While performing 'We Know Where You Fucking Live' on Sunday night, he brought out the customised microphone, while being wheeled around the stage by a stagehand dressed in medical scrubs.

Given that this happened on the same day as a horrific mass shooting in Texas, and that the city of San Bernardino had itself seen a major mass shooting in 2015, it understandably didn't go down particularly well.
In a statement, Manson wrote that, "In an era where mass shootings have become a nearly daily occurrence, this was an act of theater in an attempt to make a statement about how easily accessible semi-automatic weapons are and how seeing them has become normalized."
"My art has always been a reaction to popular culture and my way to make people think about the horrible things that happen in this world. My performance was not meant to be disrespectful or show any insensitivity."
"The prop microphone I used on stage was handed to me with the approval of a police officer. My empathy goes out to anyone who has been affected by the irresponsible and reprehensible misuse of REAL guns."
