This story seems like anti-TSA hyperbole to me. I'm not saying it didn't happen, but I seriously doubt that it ever happened, at least not in a US airport with the TSA. The lack of names, of even an airport location, plants the seeds of doubt in my mind.
I'm not defending TSA. No one has been as distrustful and critical of TSA as I have. But using falsehoods or exaggerations to criticize them is as detrimental to the cause of keeping them within the law as their own propaganda.
