The FBI says there are no additional threats related to the fugitive who was arrested in southwestern Wisconsin following a nine-day manhunt.
Milwaukee-based special agent Justin Tolomeo joined other law enforcement officials Friday at a news conference where they detailed the capture of Joseph Jakubowski.
Jakubowski is suspected of stealing an arsenal of weapons from a gun store in southern Wisconsin and of mailing a threatening manifesto to the White House.
Tolomeo says Jakubowski was found with four handguns, one long gun, multiple boxes of ammunition, a sword and containers of flammable liquid, as well as a protective vest and helmet.
He says 26 law enforcement agencies, including 250 officers, worked together to find Jakubowski, who was arrested in a farm field early Friday.
