At least 18 police officers were reportedly injured in Berlin on Saturday as they tried to break up a large gathering of people demonstrating against coronavirus restrictions, including the face mask requirement.
Some protesters carried a banner calling for the arrest of US billionaire Bill Gates, German Chancellor Angela Merkel, German Health Minister Jens Spahn, and others.
"Distancing, hygiene rules, and face masks serve to protect all of us," he wrote on Twitter.
He believed Bill Gates was behind the coronavirus and wants to forcefully vaccinate everybody and the German government is helping him to do that," von Hammerstein said.
