Three bank employees in Louisiana took themselves to hospitals Monday after coming into contact with flyers that were left in the night dropbox, authorities said.
“These flyers were dropped off to at least five other businesses in the area,” fire spokesman Justin Hill said.
A handful of other businesses in Baton Rouge were also shut down around noon, WBRZ-TV reported.
Authorities didn’t name the impacted businesses.
A hazmat crew was at the scene and was investigating, Hill said.
