Police and emergency service personnel seen during the investigation of a suspicious letter at the Unisys Payment Services in Leusden, The Netherlands.
The sender of the two letter bombs which exploded in Kerkrade and Amsterdam on Wednesday was a blackmailer demanding payment in bitcoin, police have confirmed to website Nu.nl.
The spate of letter bombs earlier in the year were also sent by someone demanding bitcoin and it is likely all the letters came from the same source, police say.
Two bombs exploded on Wednesday morning, one at an ABN Amro post sorting office in Amsterdam’s Sloterdijk and one at a Ricoh office Kerkrade.
No-one was injured at either location. A suspected third letter bomb, delivered to an ABN Amro bank branch in Maastricht, turned out to be computer mouse in an envelope.
