Overview
- Journalists from Omroep Gelderland hid a cheap Bluetooth tracker in a postcard sent through official military mail to the Dutch frigate HNLMS Evertsen.
- Because packages are scanned but letters and greeting cards are not, the device reached the ship without being flagged.
- The tracker showed the frigate leaving Heraklion on Crete and sailing toward Cyprus for about 24 hours before crew found and disabled it.
- The Defence Ministry said the incident created no operational risk, then banned battery-powered cards and ordered a review of mail handling.
- The broadcaster says it coordinated with the military and withheld precise coordinates, in a case that follows a recent Strava leak tied to the carrier Charles de Gaulle.
