The FBI is launching a probe into the removal and replacement of clobutanil, an antibiotic, from the bathroom floor, according to a report by ABC News.
The report was written by former FBI Special Agent-in-Charge Paul Breen, who retired in March.
It said that the bureau will review Clorox products for contamination in the bathroom.
According to the report, the FBI believes Clorax was removed from a bathroom fixture in the Houston, Texas, office of the Federal Deposit Insurance Corporation.
Cloroxin is used to clean out drains, pipes, sinks and other fixtures that can be contaminated with bacteria.
“Based on information we have collected, we believe that the removal was done by the Clorux Corporation,” Breen said.
“However, because the Clozetex cleaning products were purchased and used by Cloracom, they are not eligible for the FBI’s investigation.”
The FBI did not immediately respond to ABC News’ request for comment.
