CBS Denver has learned that two TSA agents at the Denver International Airport were fired in February after allegedly conspiring—on "roughly a dozen" instances—to allow one of the agents to grope the crotches of men he found attractive.

“He related that when a male he finds attractive comes to be screened by the scanning machine he will alert another TSA screener to indicate to the scanning computer that the party being screened is a female," police wrote in documents obtained by new station. "When the screener does this, the scanning machine will indicate an anomaly in the genital area and this allows (the male TSA screener) to conduct a pat-down search of that area."

Airport officials were apparently first alerted to the scheme in November of last year by an anonymous tip, but it wasn't until a supervisor observed the agents—one man and one woman—in action months later were the two fired:

On Feb. 9 TSA security supervisor Chris Higgins watched the screening area, observing the employees. “At about 0925 he observed (the male TSA screener) appear to give a signal to another screener … (the second female screener) was responsible for the touchscreen system that controls whether or not the scanning machine alerts to gender- specific anomalies, according to a law enforcement report obtained by CBS4.

According to the report, the TSA investigator then watched a male passenger enter the scanner at DIA “and observed (the female TSA agent) press the screening button for a female. The scanner alerted to an anomaly, and Higgins observed (the male TSA screener) conduct a pat down of the passenger’s front groin and buttocks area with the palm of his hands, which is contradictory to TSA searching policy.”

The female TSA agent reportedly later confessed to the plot. No victims have come forward.
