Police said it was the work of one man who entered the building of the National Gallery through a small balcony door, on a side wall, after deliberately activating alarms the night before, apparently leading a guard to leave one disabled.
Policija kaže da je krađu izveo čovek koji je ušao u zdanje Nacionalne galerije kroz mala vrata na balkonu, preko bočnog zida, pošto je noć ranije namerno aktivirao alarme, zbog čega je, kako se veruje, čuvar jedan alarm ostavio neaktiviran.
