ROCKLAND COUNTY, New York -- A 56-year-old New York man has been arrested on federal charges of unlawfully manufacturing an explosive device.
Paul Rosenfeld built a bomb in Rockland County and intended to detonate it on the National Mall in Washington D.C. on Election Day, officials said.
Sources said Rosenfeld was planning to detonate the device in a suicide bombing.
Officials said Rosenfeld wanted to draw attention to an ideology called "sortition," the political belief that the government should be selected by lottery rather than popular vote.
He was arrested by the FBI and local authorities Wednesday morning.
When authorities searched his house, they found a functional explosive device weighing approximately 200 pounds.
Law enforcement agents also found, among other things, a fusing system for triggering explosive devices and what appeared to be empty canisters of black powder.
Rosenfeld was caught after he started communicating his intentions to a person in Pennsylvania in September. That person alerted authorities.
Rosenfeld had previously constructed smaller explosive devices for practice.
