And it was announced yesterday that the Chief of police in Cologne was sacked as a response to the authorities’ handling of the attacks.
The incident has sparked a heated debate in Germany about the country’s open-door policy to migrants.
Around 1,000 demonstrators from anti-immigration group Pegida are expected to gather outside of the city’s train station today, according to police.
There was also concern that a similar incident might have taken place in Switzerland.
Zurich police revealed six women were allegedly robbed, groped and molested by a “crowd of multiple men with dark coloured skin”.
The number is unusually high for the country, which has one of the lowest crime rates in Europe.
A spokesperson for the police force added that the attacks were “a little bit similar” to the 120 cases of robbery and sexual abuse that took place in Cologne on the same night.
