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.
