The Transportation Security Administration has fired two screeners for conspiring to fondle male passengers as they came through a security checkpoint at Denver International Airport.

One of the screeners, a man, signaled to a female colleague when a man he found attractive was coming through the scanning machine.

The woman then pressed a touchscreen button indicating that the man being screened was actually a woman, according to a Denver police report of the allegations.

The scanner than alerted screeners that it had found an oddity in the area of the genitals, triggering a physical pat down of the passenger’s groin, the police report said.

In a statement, the TSA said: “These alleged acts are egregious and intolerable. TSA has removed the two officers from the agency. All allegations of misconduct are thoroughly investigated by the agency. And when substantiated, employees are held accountable.”

An anonymous employee contacted the TSA in November 2014, and told them a male screener had told her that “he ‘gropes’ males who come through the screening area,” according to the report.

The agency had an investigator observe the screening area.

On Feb. 9, the investigator noticed the male screener give a signal to the woman who controlled the touchscreen system.

When a male Southwest Airlines passenger entered the scanner, the investigator noticed the woman “press the screening button for a female,” the report said.

The male screener then conducted “a pat down of the passenger’s front groin and buttocks area with the palms of his hands, which is contradictory to TSA searching policy,” the report said.

Under questioning by the investigator, the female screener admitted that she had responded to her fellow screener’s signals at least 10 times.

She knew that doing so would allow him to perform a pat down on a male passenger that he found attractive, the report said.

TSA special agent Charles Stone contacted the police sex crimes unit on March 19 and gave a detective the information, but prosecutors declined to pursue the case without a known victim, the report said.

CBS4 broke the story on Monday.

Stone told the detective that both screeners had been fired and that all efforts to identify the Southwest passenger had been unsuccessful, and there had been no similar complaints.

Lynn Kimbrough, spokeswoman for the Denver district attorney, said the office decided not to file charges of unlawful sexual contact in April because the office and investigators couldn’t identify a victim.

But Kimbrough said Tuesday the case is being reviewed to determine if other charges may be filed.

“We were looking at it before through the narrow lens of a sex crime — now we’re broadening our perspective,” she said. “It’s possible that some other charge may be appropriate.”

Kimbrough said there are other charges that could be filed that would not require “a named, identified person as the victim.” She said the review would likely be completed within the next couple of days.
