Nine months ago in November 2022, a multi-stage heist disabled security at a German museum to steal Celtic gold coins worth almost 2 million euros. Now police say they have recovered coins and solved the case.

German police said Wednesday that four suspects were arrested.

The Bavarian Criminal Police Office announced in Munich that the suspects were arrested during a police operation in the greater Schwerin area, located in Germany’s northeastern state of Mecklenburg-Western Pomerania.

The museum lost 483 Celtic gold coins from 100 BCE. This large theft was somewhat notable due to tradecraft: regional telecommunications were cut in order to disable the museum alarm system, and the door logs recorded egress in less than ten minutes.

Organized crime was naturally suspected at first and Interpol setup a special investigation unit. Police now say more details will be released this week.
