“A grievance has been filed by the FOP several weeks back, and we’re waiting on the Illinois Department of Labor to send out a safety inspector to take a look at the conditions that are there,” said FOP spokesman Pat Camden.

Camden said it is not clear where in the building the mold located, but “it’s enough to where somebody has complained to the union in regards to it, and that’s when we filed a grievance.”

A police News Affairs spokeswoman police officials are meeting with the Chicago Department of General Services “to address a humidity issue at the academy that could cause mold growth.”

Meanwhile, Camden says the union is waiting on the Illinois Department of Labor to send out a safety inspector.

Calls to the Illinois Department of Labor were not returned.
