A German state interior minister has said people of foreign descent were responsible for virtually all of the violence on new year's eve in Cologne, adding that this included migrants who arrived in Germany over the past year.
More than 100 women reported being threatened, robbed or molested during news year's eve celebrations in the city.
"Based on testimony from witnesses, the report from the Cologne police and descriptions by the federal police, it looks as if people with a migration background were almost exclusively responsible for the criminal acts," Ralf Jaeger, Interior Minister from the State of North Rhine-Westphalia told a special commission.
"All signs point to these being north Africans and people from the Arab world," he added. "Based on what we know now from the investigation, asylum seekers who arrived in the past year are among the suspects."

A protester took to the streets of Cologne naked after a series of violent and sexual attacks against women on New Year's Eve.
Swiss artist Milo Moire braved the cold to bare all in the German city's cathedral square, holding up a sign which read: "Respect us! We are not fair game even when naked".
She said her protest was a reaction to some advice from officials warning women to keep men at arm's length, saying: "It is a matter of course we have worked for in the past 50 years, that I can live as a woman the way I want to, in freedom."
Police were on patrol in the square but did not interfere with the performance - though they did usher away a number of young men in the area around the main station and cathedral.
Witnesses have described the hundreds of men who carried out the attacks as being of "Arab or North African origin," but little concrete evidence has been released to date on who was responsible for the assaults.
