The scale of the attacks on women at the city's central railway
station has shocked Germany. About 1,000 drunk and aggressive young men
were involved.
City police chief Wolfgang Albers called it "a
completely new dimension of crime". The men were of Arab or North
African appearance, he said.
Women were also targeted in Hamburg.
But
the Cologne assaults - near the city's iconic cathedral - were the most
serious, German media report. At least one woman was raped, and many
were groped.
Most of the crimes reported to police were robberies. A volunteer policewoman was among those sexually molested.
The pretty Christmas market and medieval setting may look idyllic,
but at Christmas and New Year the area around Cologne Cathedral is a
notorious danger zone when it comes to pickpockets and theft.
Now the sexual harassment, and in one case rape, of dozens of women has shocked Germany.
What
is particularly disturbing is that the attacks appear to have been
organised. Around 1,000 young men arrived in large groups, seemingly
with the specific intention of carrying out attacks on women.
Police
in Hamburg are now reporting similar incidents on New Year's Eve in the
party area of St Pauli. One politician says this is just the tip of the
iceberg.
And there are real concerns about what will happen in February when the drunken street-parties of carnival season kick off.
Cologne
will stage carnival events in February, with hundreds of thousands of
revellers expected in the streets, as on New Year's Eve.
The police chief said "the assailants' behaviour is a real concern for me, also because of the carnival".
Police
were deployed outside the central station because of the crowds on New
Year's Eve, but failed to spot the many attacks, according to reports.
There are also fears that a number of women did not report assaults.
'Monstrous' assaults
Cologne
Mayor Henriette Reker said the attacks were "monstrous". "We cannot
allow this to become a lawless area," she said, insisting that visitors
could not come to the city fearing attack.
German Justice Minister Heiko Maas tweeted that "we won't tolerate these abhorrent assaults on women - all those responsible must be brought to justice".
One
man described how his partner and 15-year-old daughter were surrounded
by an enormous crowd outside the station and he was unable to help. "The
attackers grabbed her and my partner's breasts and groped them between
their legs."
A British woman visiting Cologne said fireworks had
been thrown at her group by men who spoke neither German nor English.
"They were trying to hug us, kiss us. One man stole my friend's bag,"
she told the BBC. "Another tried to get us into his 'private taxi'. I've
been in scary and even life-threatening situations and I've never
experienced anything like that."
The justice minister warned against linking the crimes to the issue of migrants and refugees.
Germany saw a record influx of migrants in 2015, which provoked an
intense debate on immigration and marches by the anti-Islam Pegida
movement.
Mr Maas said "the law does not discriminate regarding a person's origin or passport. All are equal before the law".
Cologne
news website Koelner Stadt-Anzeiger says the suspects were already
known to police because of frequent pickpocketing in and around Cologne
central station.
Wider problem
In
Hamburg several women told police that gangs of men had molested and
robbed them on New Year's Eve on the Reeperbahn - a street known for its
boisterous night life.
Some similar attacks were reported in Stuttgart.
A
policeman who was outside Cologne station during the New Year's Eve
trouble told the city's Express news website that he had detained eight
suspects. "They were all asylum seekers, carrying copies of their
residence certificates," he said.
However, there was no official
confirmation that asylum seekers had been involved in the violence.
Commentators in Germany were quick to urge people not to jump to
conclusions.
German n-tv news says Cologne police are considering
calling in reinforcements from other parts of Germany and installing
extra surveillance cameras, with telescopic lenses.
