Fire officials: no dangerous compounds in suspicious substance in threatening letter to Mosaic

UPDATE: The FBI says lab reports came back negative for biological threats. “As this is still an ongoing investigation, no other details can be released,” an FBI spokesman said.

PREVIOUS STORY: (WFLA) – The Lithia Mosaic office received a threatening letter with a suspicious substance Friday, officials confirmed. According to Hillsborough Fire and Rescue, the white powder tested negative for dangerous substances.

The office that received the letter is at 13830 Circa Crossing Dr. The Hillsborough County Sheriff’s Office. FBI and the HAZMAT team responded to the scene.

The substance was tested on the field by HCFR. No dangerous substance was detected. FBI took custody of the substance and took it to the local lab. The results from the lab will take several days, according to the FBI.

In mid-September a sinkhole opened up at the Mosaic property in Mulberry. That sinkhole sent millions of gallons of radioactive water into an aquifer.

Mosaic leaders and state officials have come under intense scrutiny for failing to notify nearby residents about potential dangers to their drinking water.

8 On Your Side was the first to expose the sinkhole.
