Guido Limmer, the deputy head of Bavaria’s State Criminal Police Office, described how at 1:17 a.m. (0017 GMT) on Tuesday cables were cut at a telecoms hub about one kilometer (less than a mile) from the Celtic and Roman Museum in Manchning, knocking out communications networks in the region.
Security systems at the museum recorded that a door was pried open at 1:26 a.m. and then how the thieves left again at 1:35 a.m., Limmer said. It was in those nine minutes that the culprits must have smashed open a display cabinet and scooped out the treasure.
Limmer said there were “parallels” between the heist in Manching and the theft of priceless jewels in Dresden and a large gold coin in Berlin in recent years. Both have been blamed on a Berlin-based crime family.
“Whether there’s a link we can’t say,” he added. “Only this much: we are in touch with colleagues to investigate all possible angles.”
Bavaria’s minister of science and arts, Markus Blume, said evidence pointed to the work of professionals.
“It’s clear that you don’t simply march into a museum and take this treasure with you,” he told public broadcaster BR. “It’s highly secured and as such there’s a suspicion that we’re rather dealing with a case of organized crime.”
Officials acknowledged, however, that there was no guard at the museum overnight.
An alarm system was deemed to provide sufficient security, said Rupert Gebhard, who heads the Bavarian State Archaeological Collection in Munich.
Gebhard said the hoard was of great value both for the local community in Manching and for archaeologists across Europe.
The bowl-shaped coins, dating back to about 100 B.C., were made from Bohemian river gold and show how the Celtic settlement at Manching had links across Europe, he said.
Gebhard estimated the value of the treasure at about 1.6 million euros ($1.65 million).
“The archaeologists hope that the coins remain in their original state and reappear again at some point,” he said, adding that they are well documented and would be hard to sell.
“The worst option, the melting down, would mean a total loss for us,” he said, noting that the material value of the gold itself would only run to about 250,000 euros at current market prices.
Gebhard said the size of the trove suggested it might have been “the war chest of a tribal chief.” It was found inside a sack buried beneath building foundations, and was the biggest such discovery made during regular archaeological excavations in Germany in the 20th century.
Limmer, the deputy police chief, said Interpol and Europol have already been alerted to the coins’ theft and a 20-strong special investigations unit, codenamed ‘Oppidum’ after the Latin term for a Celtic settlement, has been established to track down the culprits.
