PHILADELPHIA (KYW Newsradio) — The FBI is trying to identify a substance found on a mail-in ballot that forced a lockdown at a Chester County government building Friday morning.
Chester County District Attorney Chris de Barrena-Sarobe said it was around 10:30 a.m. when a Chester County voter services worker noticed what was described as a "non-liquid substance" on the outside of a mail-in ballot.
The county building was shut down, and the hazmat team came into the room.
“They checked for chemical and biological hazards," de Barrena-Sarobe said. "Within 45 minutes, they were able to confirm that they found none of that. The room was safe."
de Barrena-Sarobe said the ballot was never opened, and it's been turned over to the FBI for investigation.
Investigators are trying to determine whether the ballot was mailed in or placed in a drop box.
