Kaliningrad police decided to check the concert-viewers from Uzbekistan for the presence of migration documents on Saturday, according to the Noviy Kaliningrad.ru. People's artists of Uzbekistan Ozodbek Nazarbekov gave a concert in Kaliningrad on July 5. The local law enforcement agents decided to check the concert-viewers for presence of migration documents demanding the proof of identity. "You are a citizen, consequently, you must carry your ID with yourself," the news agency cited the policeman. The edition noted the raids conducted by the police during the concert were "improper" as the viewers "came for concert just to listen to music and songs."
