Thousands of pounds of mobile phones were stolen from a shop in Belper on Thursday.
Staff at Go Mobile on Bridge Street turned up to work on Friday morning to find the back door unlocked and a number of phones missing from a secure cage.
CCTV showed two people in dark clothing leaving the store at around 8pm and getting into a dark five-door 4x4, similar in style to an Izuzu Trooper. The vehicle had a tyre holder with a silver logo and a vent on the bonnet.
Anyone with information is asked to call 101.
