Pink Floyd bassist Roger Waters is being investigated by German police for incitement to hatred after he dressed up as a Nazi during a performance in Berlin.

Waters, 79, wore a long, black trench coat decorated with red armbands and metal insignia on his collar reminiscent of an SS officer while on stage at the Mercedes-Benz arena last week. During the performance, Third Reich-style banners also hung from the stage while an inflatable pig emblazoned with the Star of David floated above the audience. 

Waters is a well-known pro-Palestinian activist who has been accused of holding anti-Jewish views. He has floated an inflatable pig emblazoned with the Star of David at his concerts in recent weeks as part of his ‘This is Not a Drill’ tour.

During the concert last week, a screen behind Waters displayed the names of Anne Frank and Abu Akleh, an Al Jazeera journalist who was fatally shot last year while covering an Israeli Defense Forces raid on a Palestinian refugee camp. Germany’s Orthodox Jewish rabbinical association has called for a ban on Waters performing in Germany — but the rocker continues to deny he is anti-Semitic and is only speaking out against Israeli politics.  And some city officials have tried, unsuccessfully, to ban Waters from performing in Germany due to his controversial views.  Throughout his performance last week, Waters tried to draw comparisons between Nazi Germany and present day Israel as he doubled down on his criticism of the country’s treatment of Palestinians.
