Chicago Police spokesman Anthony Guglielmi told CBS Chicago that Hartman slipped through a TSA checkpoint before taking a shuttle to an worldwide terminal. She was also banned from possessing firearms and is not allowed near O'Hare, per the judge's orders.
Sources told CBS Chicago that O'Hare security video shows Hartman had been wandering the airport for two days and no one questioned her. She was returned to Chicago and taken into custody immediately at O'Hare Airport.
She landed on Monday, Jan. 15, before being detained by British Customs officials and sent back to Chicago on Thursday, Jan. 18.More news: Rapper Kodak Black arrested again after police raid his home
In 2014 she was arrested three times.
She apparently tries to blend in with large groups to get past airport security, according to previous reports.
After sleeping overnight in O'Hare's global terminal, she somehow made it past British Airways staff and a Customs and Border Patrol office. A TSA spokesman said in a statement Friday they were looking into the matter as to how Hartman was able to walk past the security.
She added in a statement: "We are working with our law enforcement partners to support a comprehensive and thorough investigation, while continuing to maintain the highest levels of security at O'Hare Airport".
In 2016, she was sentenced in Chicago to six months of house arrest and placed on two years of mental health probation. "During the initial investigation it was determined that the passenger was screened at the security checkpoint before boarding a flight".More news: Risky travel likely with near blizzard conditions — Monday Madness

Hartman claims she is homeless and feels safer in airports than on the streets.
According to CBS sources, CCTV cameras captured Hartman, of Hamelitz Court in Grayslake, U.S., as she wandered around the airport for two days without being confronted by security.More news: Meghalaya Governor Awaits EC View on 17 MLAs' Disqualification
