JACKSONVILLE, Fla. — A person is expected to be OK after having a reaction to some sort of substance sent inside a letter to the State Attorney's Office for the 4th Judicial Circuit Monday, according to the Jacksonville Fire and Rescue Department.
However, the FBI says preliminary laboratory results have concluded that no biological threat was detected. Multiple agencies are still investigating.
The Jacksonville Sheriff's Office says units responded to the 200 block of Forsyth Street shortly before 3 p.m.
FBI Jacksonville, together with the U.S. Postal Inspector, Jacksonville Sheriff's Office and Jacksonville Fire Rescue Department, are investigating the letters.
JFRD says a person had a reaction on his arm to something in the letters. That person is expected to be OK. The FBI says the letters contained a substance that is currently being tested at a local laboratory.
"We are working with our partners and the SAO to ensure the safety of all employees as we expedite the testing process," said the FBI in a statement.
