About 70 artifacts and art pieces were vandalized at several museums in Berlin earlier this month.

Ancient Egyptian sarcophagi, stone sculptures and 19th century paintings are among the works damaged wtih an oily substance on Oct. 3, according to Berlin police. The museums were open that day in celebration of the 30th anniversary of German Reunification. The damage was not immediately revealed early in the investigation. Police this week sent an appeal via email to museum visitors registered for that day in a search for witnesses. 

Some news agencies have described a possible link between the crime and conspiracy theorists who deny the coronavirus epidemic and claim that "the Pergamon Museum is the center of a 'global Satanism scene' which...Chancellor Angela Merkel has been using for 'human sacrifices,' noting that she lives opposite the Museum," as reported by NPR.

The Pergamon Museum, Neues Museum, and Alte Nationalgalerie are a few of the affected museums.
