A large box with an unknown substance inside was delivered to the St. Johnsbury office of U.S. Sen. Bernie Sanders Tuesday afternoon, causing a building evacuation until a hazardous materials team could determine whether there was a dangerous chemical inside.
St. Johnsbury Police responded to the Western Avenue office building along with the St. Johnsbury Fire Department and CALEX rescue personnel.
The box could be seen from the top of the driveway to the rear lower entrance of the building where Sanders' office is staffed by Sheila Reed. The box was outside the building.
Firefighters stretched "Do Not Cross" tape across the top of the driveway and police officers went through the building asking all occupants to evacuate. There are four other professional offices in the building.
The haz mat team was due to arrive to assess the contents of the box and determine whether a threat existed.
