A 45-year-old Homeland Security employee in Pennsylvania was arrested after authorities say he walked into the agency’s headquarters with a gun, knife, pepper spray, handcuffs and an infrared camera in June.
Leigh Wienke, who is a federal government analyst, was charged with illegally building a silencer on an unregistered pistol, along with six other counts. He faces up to 10 years in prison, NBC Washington reports.
Security officers found Wienke with the weapons at the headquarters on Nebraska Avenue in northwest D.C.
Agents said in the court filing that there was “probable cause to believe Jonathan Wienke was conspiring with another to commit workplace violence, and more particularly may have been conspiring or planning to commit violence against the senior DHS officials in the building.”
