Chicago Police spokesman Anthony Guglielmi says Marilyn Hartman was flown back to Chicago on Thursday night and taken into custody once she arrived.
"During the initial investigation it was determined that the passenger was screened at the security checkpoint before boarding a flight", the Transportation Security Administration (TSA) said in a statement.
Hartman has been detained several times across the country for trying to bypass airport security.
Upon realizing that Hartman had made it onto the plane without being noticed, the airline warned Heathrow airport officials that they had a stowaway on the incoming flight.
And earlier this month, she showed up in London.
Hartman's movements through the airport were captured on high-definition surveillance video, according to authorities.
Sources told CBS 2 Chicago that Hartman slipped by a distracted TSA agent in O'Hare Terminal 3, somehow made it to the global terminal and slipped past a busy gate agent to board a British Airways flight to London. In 2016, she was sentenced to another two years of probation and six months in a mental health facility after she was caught trying to sneak on a flight.

In 2015, she told investigators that she had boarded a plane in Minnesota without a ticket and flew to Jacksonville, Florida, according to an arrest report obtained by NBC News. "Upon learning of the incident, TSA and its aviation partners took immediate action to review security practices throughout the airport".
With neither a ticket nor a passport, Marilyn Hartman slipped into Chicago O'Hare International Airport last week, sneaked onto a British Airways flight and traveled to London, where she was apprehended by customs officials, the Chicago Police Department said in a news release.
After sneaking onto a flight from San Jose to Los Angeles in 2014, she told reporters she was remorseful. I don't want to help the enemy.
She's been characterized as a homeless loner who drifted up and down the West Coast for 10 years, sleeping in women's shelters and motels. In that incident, she slipped past an agent who was checking a family's boarding passes at Mineta San Jose International Airport, went through electronic security screening and then somehow got past a gate agent. She served 23 days in jail.
Hartman's current residence of record is a senior living neighborhood, Lakefront Residences of Grayslake, Illinois.
Dressed in a dark gray sweater and wearing black-framed eyeglasses, Hartman said nothing during the hearing, but her lips curled into a smile after the judge granted her release. She is banned from O'Hare and any British Airway aircraft.
Hartman also will be required to have an ankle monitor until the conclusion of her case.
