Police notes taken by officers at the New Year's Eve Cologne sex attacks reveal the full, horrific detail of how women were groped, sexually assaulted, robbed and raped at the hands of a vicious sex mob.

Over 500 women were attacked by baying groups of immigrant men in a free-for-all of humiliation and degradation which overwhelmed officers and at a stroke undermined Germany's vaunted role as protector of refugees from war and terror.

Disturbing reports are recorded in the terse argot of police officers - but leave no room for misinterpretation.

One of the first victim's to speak out, an 18-year-old named Michelle (pictured, in the square outside the main train station where she was attacked), described being surrounded by a group of 30 'angry' men who groped her and her friends then stole their belongings as they fled

Assaults: More than 500 women were attacked by groups of immigrant men in a free-for-all of humiliation on New Year's Eve. Police in Germany have released notes taken from victims of that night

The notes reveal how women complained they were surrounded by sexually frustrated men who tried to put their hands inside their tights and knickers and tried to put their fingers in their vaginas.

One woman told police she was surrounded by 20 men of North African appearance before they attacked her intimate parts.

A victim said she was pinched in the crotch, while another said hands were 'all over her breasts and buttocks'.

Thieves rifled through a woman's handbag while others distracted her by shoving their hands underneath her clothes.

In an appalling catalogue of complaints, the women who were attacked by up to 2,000 men during a fireworks display in the square by the cathedral in front of Cologne's train station told how they had mobile phones, bank cards and cash stolen.

One reads: 'Several injured women. All suffered attempts to introduce fingers in vaginas, tights. All were touched on the chest and buttocks. Finger was introduced inside a victim.'

Groping hands tugged and ripped at their clothes in what is a gang-rape phenomenon known as 'taharrush gamea' in the Arab community – which happened on that fateful night in Cologne and has spread across other parts of Europe including Sweden, Finland and Austria.

The name of the practice translates to 'collective harassment' and is carried out by large groups of men who sexually assault lone women, either by groping, or in some instances, raping them.

The attacks in which women described having hands being pushed between their legs was part of an unprecedented attack and one in which Angela Merkel, who allowed 1.1 million migrants into Germany last year, was 'out of control'.

'Scarred for life': 'Jenny' was just one of the Cologne New Year's Eve victims. She was left with horrific burns on her shoulder after a firework was shoved into the hoodie she was wearing. Many more came forward to tell police what happened to them that night. The police log started with the first complaint at 10.30pm

Police notes show the full scale of the horror of that happened to victims in Cologne. One note read: Female victims: two victims were surrounded at the entrance to the station by a group of people and assaulted in the genital area; two fingers inserted into the vagina'. Victim Michelle (pictured on German TV) said her and her friends were surrounded and hand their purses stolen

Another distressed victim (right), who did not want to be named, told German TV how she was 'groped between the legs' after a gang of around 40 men surrounded her and her boyfriend during the harrowing attacks

It made parts of Cologne a 'no go' zone for women. Cologne mayor Henriette Reker added to the controversy when she advised women to fend of potential sex attackers – by keeping men at 'an arm's length'.

Women like 18-year-old blonde Michelle who said she and a group of friends were sexually assaulted by marauding men.

Michelle said they were chased, surrounded and had their purses stolen – adding: ‘The men were full of anger, and we had to make sure that none of us were pulled away by them. They were groping us and we were trying to get away as quickly as possible.’

‘We were fondled, I was groped between my legs. My friends were also fondled. There was quite a big group of people, maybe 30 or 40,’ said another victim.

Here, the police notes from that night, which begin with the first complaint at 10.15pm and peak at around 1am, with the last statement made at 4.15am, catalogue the true scale of what happened to those women on December 31.
