Red Line train evacuated during evening rush due to unauthorized person on tracks

CHICAGO (CBS) -- A CTA Red Line train was evacuated in the State Street subway Friday evening due to an unauthorized person on the tracks.

Reporter Aaron Gettinger of the Hyde Park Herald tweeted a photo showing a crowd of people walking down the subway tunnel toward the Harrison stop.

The person got onto the tracks near the Grand Avenue stop, the Chicago Transit Authority said.

Further information about what happened was not immediately available.

For a period of time, the Red Line was rerouted from the subway under Clybourn Avenue, Division Street, and State Street to the Brown and Purple Line tracks and the Loop 'L.'

By 5:55 p.m., Red Line service was back to running normally through the subway.
