On 7 January, several anonymous police officers from Cologne denied statements that the police did not know the nationality of the perpetrators; they told the press that "most of them" would have been freshly arrived asylum seekers.
Jürgen Mathies, the new Cologne police chief, said many of the perpetrators were from countries where they might be familiar with "this behaviour, where women are hemmed in and then abused by a large number of men at once".
According to Albers, who was subsequently transferred to provisional retirement for his handling of the situation, the alleged perpetrators were all men "of Arab or North African appearance" between the ages of 15 and 35, who could not speak German.
In several cases, a finger was inserted into the vagina of the victim—which constitutes a rape under German law—after her clothes were torn from the body.
Groping, insults, and rape were often combined with robbery and theft.
