An activist group projected a photo of billionaire Elon Musk making a controversial gesture that resembled a Roman salute on a Tesla factory near Berlin this week, with a single word above the world’s richest man: “Heil.

They projected the words “heil” and “boycott” alongside the large Tesla logo, as if to read “heil Tesla” or “boycott Tesla" on to the nine meter high building on Wednesday night

Elon Musk, the world's richest man and a close ally of President Donald Trump, has faced widespread accusations of making a Nazi gesture twice during a speech to a crowd of Trump supporters gathered at Washington's Capital One Arena for an indoor "Presidential Parade" on Monday, shortly after Trump's second inauguration.

Left-wing activists have projected a giant image of Elon Musk doing a gesture that has been likened to a Nazi salute alongside the word “heil” onto Tesla’s Berlin factory.

Authorities in Germany are investigating a controversial image projected onto the Tesla Gigafactory in Grünheide, near Berlin.

Campaign group Led by Donkeys has projected the clip of Elon Musk making two ‘Nazi salutes’ at Trump’s inauguration onto the side of his Tesla factory in Berlin. The video featured Musk making the gesture alongside the words “Heil Tesla”, a reference to the Nazi greeting used to pay homage to fascist leader Adolf Hitler.

Led By Donkeys teamed up with German activist group Center for Political Beauty to beam the hand gesture onto a Tesla building in Germany.

The world doesn't seem quite ready to let Elon Musk move on from the salute he made at Trump's inauguration. It's already been adopted by anti-Musk protestors, who projected it onto a Tesla plant in Berlin ahead of the impending federal election.
