CHICAGO — A suspect was taken into custody after a man was stabbed on a downtown CTA Blue Line train Thursday afternoon.

Around 4:30 p.m., authorities responded to the Monroe Blue Line in downtown Chicago. Authorities said a 42-year-old man was stabbed on the CTA train then walked to the Chase Bank building. He was stabbed in the leg and lower back and transported in critical condition.

As a result of the stabbing, Blue Line service was temporarily suspended downtown from Grand to UIC-Halsted.

People who work in the Loop said safety on public transportation can be frustrating, but staying aware of surroundings is the best thing they can do.

“I grew up on the West Side of Chicago, the train is the best way to get to the city,” said Chardel Pickett. “It’s kind of like ‘wow’, I’ve got to watch out now.”

Dearborn was blocked off between Madison and Monroe for the investigation.

Charges against the man are pending
