A waitress at the upscale Aviary cocktail bar in Chicago’s West Loop was taken into Secret Service custody Tuesday night for allegedly spitting on Eric Trump.

She was immediately handcuffed and detained by the Secret Service and the Chicago police, , according to the New York Times. She was released after about two hours when Trump, son of President Donald Trump, decided not to press charges.

The Secret Service has declined to comment on the incident.

However, Eric Trump told the conservative website Breitbart that “it was purely a disgusting act by somebody who clearly has emotional problems."

Anthony Guglielmi, a Chicago Police Department spokesman, confirmed on Twitter that local officers assisted the Secret Service at the bar but declined to discuss what happened.

“Any and all inquiries regarding a federal protectee must be directed to the Secret Service,” he said.
