Hardly any North Africans in Cologne at New Year
Among the large groups of men who went to the New Year celebration in Cologne this year came, there appear to have been hardly any North Africans. This is in contrast to what the German police said before. …
After the New Year events there was commotion about a tweet by a policeman, in which he labeled a large group of men as ‘Nafris’, abuse for supposedly criminal North Africans. …
The police investigated whether among the men were persons accused of the assaults on New Year a year ago. But there is no evidence for that. “None of the suspects of Cologne in 2015-2016 and none of the 75 persons who had then received an exclusion order have been reported this year,” said Police Chief Mathies in a press release.
