The Cologne Lobby for Young Women told state investigators there were two cases of rape on the night when hundreds of women were molested and robbed by marauding gangs of immigrant men. The pregnant woman decided to have a termination - but admitted she was not 100 percent sure if her attacker was the father of the unborn child. "She found out she was pregnant but wasn't sure that it had happened on this night," a spokesman for the group said.

Frauke Mahr from the Cologne Lobby for Young Women told lawmakers the woman's story and said there was a hushed silence when she related it. Until now women in Cologne on the last day of the year had reported being penetrated by men with their fingers, which is also classified as rape under German law. But this was the first case of full sexual intercourse on the night in question.

The 18-year-old said that on New Year’s Eve, she had gone out with a group of friends and found herself separated from them in the crowd. She said a group of men then surrounded her and pushed her back and forth "like a ball." Eventually she landed on the ground and one man "forced himself upon her." "She said she also saw another girl near her, also laying on the ground and being attacked," said a spokesman for the group.

But a police officer saw what was happening and dragged the man off the woman, who then fled to her home near the city before deciding to go to hospital later. Neither she nor the second rape victim reported their ordeal to police. News of the abortion came on the same day that Germany revealed 2015 was a record year for immigration into the country.
