During the investigation it was found out that the most attractive metro line for pickpocketers is Koltsevaya line. Criminal's activity is noted at  the stations "Kievskaya", "Komsomolskaya", "Kurskaya", "Prospekt Mira", "Belorusskaya", both circular and radial ones. Interestingly, four of them - Kievskaya, Komsomolskaya, Kurskaya, and Belorusskaya - connect metro users with railway stations.

The police also added that pickpocketers tend to "work" near large trade centres, railway and bus stations. That's why one has to be very cautious at stations "Biblioteka imeni Lenina", "Yugo-Zapadnaya", "Shelkovskaya", "Teplii Stan" and "Vykhino".

The safest metro lines are Filevskaya and Lyublinskaya lines, and the station with the least theft quantity is "Oktyabr'skaya".
