However, her friend admitted to having a sexual intercourse with Lisa a few months earlier, German police conducted criminal investigations of two men, one a Turkish citizen and one a German citizen of Turkish origin, because such contact would be a criminal offence under German law even if happened voluntarily.[1] The incident led to intensive media reporting, especially in Russian media, and to diplomatic tensions between Germany and Russia. The Russian foreign minister, Sergey Lavrov, accused German authorities of hushing up the case.[2] German foreign minister Frank-Walter Steinmeier rejected the allegations and warned Russia of "politicising" the case.[2][5] After the Russian media extensively covered the story and claimed that the girl had been mistreated and held as a "sex slave", many Russian Germans held demonstrations in several parts of Germany, amongst others in front of the Bundeskanzleramt in Berlin on 24 January.[2]
