NASHVILLE, Tenn. » A federal air marshal has been arrested and accused of taking cellphone photographs underneath women’s skirts as they boarded a plane at Nashville International Airport.

Assistant Supervisory Air Marshal in Charge Michael Pascarella told The Associated Press that Adam Bartsch was immediately removed from duty and is in the process of being suspended or fired.

Nashville police say Bartsch was on duty on Southwest Airline Flight 3132 on Thursday when a witness noticed he was taking the photos and grabbed his cellphone. Police say the witness notified a flight attendant and Bartsch was taken off the flight and charged with disorderly conduct.

Pascarella says TSA is assisting with the investigation.

"TSA does not tolerate criminal behavior," Pascarella said.

Bartsch is due in court Nov. 14.
