CHICAGO -- Marilyn Hartman, the so-called "serial stowaway" who has tried to sneak past security at Chicago airports several times, was arrested again.
Hartman, 64, was allegedly at a bus shuttle center at O'Hare International Airport when she was taken into custody around 2:30 p.m. Wednesday.
She was charged on a trespassing violation and ordered held on $100,000 bond.

She successfully snuck onto a plane in San Jose in 2014 and was arrested when it landed in Los Angeles. And just days after her release, she was arrested again at LAX.
Recently, Hartman was confined to a locked mental health facility. But earlier this month, a judge allowed her to transfer to another facility, which allowed her more freedom.
She has had several odd confrontations with police at airports across the country and has spent at least 145 days in jail.
As part of Hartman's mental health probation, she was ordered to stay away from Chicago's airports.
