Miami-Dade County Police and federal agents appear to have evacuated a USPS mail sorting and distribution center in Opa-locka Thursday night.
Police officers and K9 units were seen at the property as trucks continued to enter the facility business as usual.
At around 10:15 p.m. Thursday, a driver told members of the media that everyone was being asked to leave. Shortly after, a group of people who appeared to be employees were escorted out of the facility.
Officers were seen entering the building with what appeared to be SWAT gear.
A CNN report stated two law enforcement officials close to the investigation said the suspicious packages sent to prominent Democrats went through the South Florida mailing center.
The FBI has not confirmed the Opa-locka facility is part of the investigation but said that multiple agencies coast to coast is involved in actively tracking more potential suspicious packages.
