A TSA spokeswoman said that Livingston, of Manassas, was hired in 2002 and that all employees submit to background checks. She said his employment expired at midnight Feb. 15. “The alleged off-duty conduct of this individual is unacceptable, and in no way reflects the integrity and professionalism” of more than 50,000 security officers, TSA said in a statement.

The case dates to the night of Feb. 15, when police were called to a Crowne Plaza Hotel. A manager told them about suspicious activity she had seen in the lobby and outside Room 506. Officer Paris Capalupo found that the room was registered to Livingston, who paid cash, according to arrest records.

The hotel manager told Capalupo that men had been gathering in the lobby. Livingston, who had key card to access the elevator, would come and get them, police said. She also said Livingston had been a guest in the past and that groups of people had entered and exited his room. By mid-February, she “became suspicious because this behavior is not typical of Crowne Plaza Hotel guests,” Capalupo wrote in an arrest affidavit.

The manager and police officers went to Room 506, where she knocked on the door, court papers say. Livingston opened it, and the manager told Livingston that she thought prostitution was going on inside. “Livingston advised that no such thing was occurring,” Capalupo wrote.

Livingston invited the manager and officers into the room, where they “observed 11 people inside the room to include three naked females and four males attempting to get dressed,” Capalupo wrote. “Multiple people were laying on the two beds, and other people were sitting in chairs and standing in the room.” One man said he paid $100, according to police.
