This is the second time this happened:
Police took two men into custody because they refused to cease their peaceful expression of solidarity with Israel by displaying an Israeli flag. (Original in German)
This is what happened the first time:
“The police acquiesced in the demand of the mob.” German police aids Jew-hating Muslim mob, removes Israeli flag from window: Â as you can see from the video, the mob applauded, cheered, and shouted “Allahu akbar” when the flag disappeared.
