German police are investigating anti-Semitic images depicting Anne Frank wearing a Schalke shirt after Lazio ultras did the same in an anti-Semitic gesture toward Roma.
DW Sports' Matt Ford shared the images, which have been attributed to Borussia Dortmund fans:
According to the Mirror's Alex Smith, however, it is not yet known who produced the mock-up, with Schalke also maintaining rivalries with Bayer Leverkusen, Cologne, Borussia Monchengladbach and Dusseldorf, where the stickers were discovered.
The images come after a similar incident in Italy last week, in which Lazio ultras posted images of Frank in a Roma shirt around sections of the Stadio Olimpico.
