German police announced today Friday that they have launched an investigation against Roger Watersbecause the Pink Floyd co-founder wore a Nazi-style costume on stage at the Mercedes-Benz Arena where he performed his concert in Berlin.

The 79-year-old Briton was not immediately available for comment. Social media users defended him, saying the performance was a satirical re-enactment of scenes from the film of the band’s hit album “The Wall,” a critique of fascism.

Footage from the May 17 concert shows the famous singer and bassist wearing a long trench coat reminiscent of a Nazi uniform, and holding an imitation machine gun aimed at the audience.

The uniform included a swastika-like emblem of two crossed hammers – iconography that was also in the costumes in the 1982 film starring rock star turned activist Bob Geldof.

Nazi symbols, flags and uniforms are banned in Germany. Waters is being investigated under a separate law on suspicion of “public incitement”, police said.

The uniform Waters wore “could be judged to violate the dignity of the victims, as well as to condone, glorify or justify the violent and arbitrary yoke of the Nazi regime in a way that disturbs the public peace,” a police spokesman said.

Other German cities, including Munich, Frankfurt and Cologne, tried to cancel Waters’ concerts as Jewish organizations, including the Central Jewish Council, accused him of anti-Semitism.

Waters is a member of the Palestinian-led “Boycott, Divestment and Sanctions” movement. directed against Israel due to the occupation of territories where the Palestinians seek to obtain statehood.

He denied the accusations against him and attempts to cancel his concerts were not crowned with success. Waters’ final German tour stop, Frankfurt’s Festhalle, on May 28 is still listed on the artist’s website.

Fans and other social media users said Waters had worn the same outfit to previous concerts.

“It clearly represents Pink from The Wall (1982), in which Bob Geldof descends into a drug-addled fascist fantasy in a film that Condemns fascism. Absurdity”, tweeted Joseph Attard, a podcast host.
