(Reuters) - The U.S. Transportation Security Administration (TSA) said on Tuesday it suspended two agents after it became aware of an “offensive display” in a baggage screening area at the Miami International Airport, saying it would not tolerate racist behavior.

The federal agency, which provides security screening at U.S. airports, did not describe the display. But an unnamed TSA employee told CNN that it consisted of two stuffed gorillas hanging from a noose on a pole.

The unidentified employees were placed on administrative leave after the display was discovered, TSA said. It was removed and an investigation was launched, the agency said in a statement.

“TSA does not tolerate racist or offensive behavior and those found responsible will be held accountable for their actions,” TSA said.

Three agents who found the display in a non-public area for screening checked luggage notified their manager, but the supervisor initially sought to downplay the incident, calling it “just a joke,” CNN reported.
