London: A teenage Russian-German girl has accepted that she made up a story about being kidnapped and raped by migrants in a case which triggered a furore in Germany and briefly embroiled Berlin police in a spat with the Kremlin, said state prosecutors.

According to The Guardian, the parents of the girl, named Lisa, reported her missing on January 11 after she failed to appear at school in the Marzahn district of the capital.

She reappeared 30 hours later with injuries on her face, and told her parents she had been attacked by men of Middle Eastern or north African appearance.

News of the incident spread on social media, sparking outrage among Berlin`s Russian-German community.

He said the teenager had been scared of going home after the school had contacted her parents over an incident at school.

Yet the allegations caused uproar in Berlin, particularly after reports of mass sexual assaults allegedly carried out by migrants in Cologne .

Analysis of the teenager`s mobile phone records showed she had spent the night with a friend, who is not being treated as a suspect.
