A 20-year-old College of Dupage student who was last seen leaving a River North bar early Sunday morning has been located and is safe, Oak Brook Police tell NBC Chicago.
A family spokesperson and police did not offer any details on where Katie O'Connell may have been.
O'Connell's case is still being considered an active investigation and details of the incident will not be released, said Police Chief Tom Sheahan in a statement.
Criminal and civil actions are being considered against any person(s) involved, police said.
O’Connell left the Underground, located at Dearborn and Illinois, early Sunday morning, telling friends that she was tired and was going to catch a cab home. Her family said she never made it there, and launched a frantic search for her.
"This is not normal behavior for Katie," one family member wrote in an email sent to media outlets. "She always contacts her family."
