Cologne's police chief has been removed from his post amid criticism of his force's handling of a string of sexual assaults and robberies carried out by groups of men in the German city on New Year's Eve. His enforced departure came as a witness to the violence told the Guardian the events appeared to have been coordinated. Lieli Shabani, 35, said she saw three Arabic speaking males who were clearly giving instructions". A leaked police report [describes] how officers were initially overwhelmed by events outside the city's train station, after which more than 100 women filed criminal complaints of sexual assault and robbery, including two accounts of rape. Cologne mayor Henriette Reker suggested on Friday that police had held back information from her, and said in a statement that her "trust in the Cologne police leadership is significantly shaken". The leaked police report, obtained by the German newspaper Bild, said women were forced to "run a gauntlet ... beyond description" to reach or leave the station. The incidents in and around the square in front of the main train station have led to accusations of a police and media cover-up. Evidence has emerged that similar attacks had taken place in seven other German cities.
