Two cash machines in canton Jura were destroyed by explosives yesterday morning at the same time.
One was at the post office at the train station in Porrentruy and the other at the Banque Cantonale du Jura in Alle.
In both cases, the robbers fled in several vehicles.
Cantonal investigators are being helped by the federal police, munitions experts from the military and forensic officers from canton Zurich.
No one was hurt in the attacks and it’s currently unsure how much money the thieves got away with.
Police are asking for anyone with any information to contact them.
