Two letter bombs exploded in the Netherlands on Wednesday and an anonymous criminal is asking for a Bitcoin payment to prevent future attacks, Dutch police say.
The first bomb went off at a postal sorting office in ABN Amro bank in Amsterdam on Wednesday morning. The letter bomb exploded moments after a mailroom worker tossed away the package. “The colleague who was sorting the mail heard a hissing sound, and threw the package away,” Mr. van der Varst said.
