CHICAGO (CBS) — A person was finally free Monday morning, after getting stuck in an elevator twice, and for more than three hours, in a downtown building.

It started around 9:15 p.m. Sunday, when a person got stuck in the elevator off the 20th floor of the Mid-Continental Plaza building at 55 E. Monroe St.

Rescue crews apparently tried to free the person through another elevator. But that elevator, and the firefighter who was helping, got stuck too.

Eventually, both the trapped person and the firefighter were freed with no injuries.

The 49-story Mid-Continental Plaza building recently converted its top 15 floors into a condominium development called the Park Monroe, which carries an address of 65 E. Monroe St. The lower floors are still used as office space.
