A brother in Cologne decided to advertise his business using the flags of all the countries taking part in the upcoming world cup soccer tournament. The ad was a 24 meter by 8 meter picture on the side of the brothel. After Muslims complained about the Saudi and Iranian flags being displayed, the owner of the brothel removed it by painting it over with black paint.
According to a police spokesperson “The group of Muslims saw it as an attack on their religious feelings that as a result of the usage of these flags in this ad were seriously threatened"
