After multiple requests to exterminate bed bugs from Buffalo's Rath building, a new threat is being investigated.

According to WIVB-TV, an investigation is beginning after an Erie County employee asked the state department of labor to look into multiple cancer cases that have occurred on just a few floors of the county office building.

At this point, air quality tests that have been done in the building have uncovered no cancer causing toxins.
