Federal prosecutors on Thursday charged a 29-year-old Tunisian citizen with producing a biological weapon after police found highly toxic ricin in his apartment in the western city of Cologne.
Special police and fire units found the ricin during a raid of his home late on Tuesday.
Security services first became suspicious after H. ordered 1,000 castor seeds — the main ingredient for producing ricin — and a coffee grinder from an online store in mid-May, prosecutors said.
