( CNN ) Two Transportation Security Administration screeners have been fired after conspiring to grope attractive men at Denver International Airport , Denver police said . Here 's how police say the scheme worked : When the male TSA officer noticed a man he found attractive , he would alert a female TSA officer . The female officer would then tell the screening machine that a female passenger -- not a male -- was walking through . And that information would trigger a machine to register an anomaly in the groin area , prompting the male TSA officer to pat down the passenger , police said , citing a TSA investigation . But during the patdown , the male TSA officer used the palms of his hands to touch the passenger 's front groin area and buttocks , which violates TSA policy . Former TSA agent sentenced for recording coworker . All this came to light after an anonymous tip from a TSA employee in November . The agency launched an investigation , and investigator Chris Higgins monitored the two TSA officers in question , Denver police said in a report . Higgins watched the plan being carried out on February 9 . He interviewed the female TSA officer , who said she had done this with her colleague at least 10 other times , police said . Both of the TSA officers investigated have been fired , TSA special agent Charles Stone told police . Authorities did not release their names . Giant security gap at airports : Lack of criminal background checks . The TSA called the incident deplorable . `` These alleged acts are egregious and intolerable , '' the agency said in a written statement to CNN . `` All allegations of misconduct are thoroughly investigated by the agency . And when substantiated , employees are held accountable . '' But it 's unlikely criminal charges will be filed because there is no identifiable victim . The TSA said it has been trying to identify the passenger in the February incident but to no avail . The TSA said no passengers have come forward with similar cases so far at the Denver airport . Hidden cameras reveal airport workers stealing from luggage . CNN 's Tony Marco contributed to this report .
