Illegal migrant from Ethiopia was detained in the check point “Mostyska – railway station” (Lviv). The passenger of the train “Kyiv-Wroclaw” presented not his passport for the check – it was one of the 18-year-old citizen of Great Britain. The photo in the document was similar to one of the bearer. The border guard manifested the substitution. The violator was taken off the train and was delivered to sub-division of State Border Service of Ukraine. The traveller confessed that he was 19-year-old citizen of Ethiopia and arrived to our country for studies on legal basis. However, in fact, he did not plan to become a student. The young boy intended to get to Great Britain where his brother lives. According to the words of detained refugee, he had bought this foreign passport at home land.
