ABSTRACT:
An anti-theft box (100) for protection of goods comprises a main body (110) defining an inner space for the goods to be protected, a lid (120) closing said main body (110), an alarm transmitter triggering a central alarm in case the anti-theft box (100) passes an alarm gate, and a releasable lock (140 145, 150, 160) locking the lid (120) to the main body (110). The anti-theft box according to the invention also comprises an internal alarm circuit (200) that is controlled to be fused when the releasable lock (140 145, 150, 160) is in a locking position and defused when the releasable lock (140 145, 150, 160) is in an unlocked position. The internal alarm circuit (200) comprises a first switch (210), which in the fused state is arranged to trigger the alarm circuit to emit a sound signal in case the first switch (210) indicates that the lid (120) and the main body (110) are separated.
