Once on the grassy area, the man called US Capitol Police, Sergeant Anna Rose of the US Park Police Department told WRC. He said he wanted to warn people of his exposure to anthrax.
Law enforcement detained the man shortly after he called them, Rose said. Police deployed a robot to inspect the truck.

The driver was escorted in handcuffs to a decontamination tent, where he was hosed down by DC fire crews, according to WTTG’s Van Applegate.
The man says he is a farmer who was spreading the substance on a field when he was exposed to anthrax.
