Video shows the suspects demanding the man's ID, then taking the victim's wine bottle and striking him in the head, leaving him bleeding in his seat.
The incident happened early Sunday morning on the Red Line train near the 95th Street station, leaving TeShaun Terry - who recorded the violent confrontation - stunned on her way home. She said she went searching for help at the train station, but no one was around.
"When I seen the blood I instantly felt so bad!" Terry said. "So, I instantly ... when the train stopped, I stopped the video and I ran upstairs to look for the operators. There were no operators! There were no security! There were literally no one!"
Terry said the two men targeted a man who appeared to be asleep on the train. The CTA attack was caught on camera before two men are seen getting away with the victim's belongings.
Chicago police shared photos of the two people they're looking for in the violent robbery around 3 a.m. No one is in custody.

The attack comes as the CTA and Chicago Police are pledging more patrols on the transportation system.
In a statement, CTA officials said: "With regards to the use of K-9 security teams, there are currently 24 teams scheduled to patrol CTA properties at any given time, which complement more than 300 unarmed guards."
Chicago police continue to search for the suspects, who Terry believes could strike again.
"They told us, they said, 'That's how you rob a person! We do this all the time!'" Terry said.
The CTA also touted a boost in ridership Monday, rising above 900,000 riders for the first time since before the pandemic. CTA officials went on to say it's impossible to have officers on every train and bus in the city.

People are scared. That's the sentiment among riders ABC7 spoke with at the 95th Street Red Line station.
"Actually I have anxiety and it's really been getting to me, riding the train by myself," CTA rider Breann Carroll said. "It's just a lot and I kind of do fear for my life. But I don't really have another way to get to work, so what do you do?"
"You try to go to work, pay your taxes and pay your bills, and this is what you have to go through?" Activist Bishop Anthony Scales said. "Every day? When is it going to change?"

A volunteer group of activists called the Untouchables are crime fighters in their 50s and 60s. They're trained in martial arts and some are former military members they said.
They're riding the CTA trains in the early morning hours to keep people safe.
"We ride from here all the way down to the end of the line at Howard. And we do it three times, come back and forth," activist Eric Lewis said.
It's an attempt to protect the people of Chicago, they said, who are growing more concerned over their safety.
"We'll be out here as long as it takes to curb the violence in the city because during the winter months it's going to get even worse and we're not standing for it," Lewis said.

"Somebody's got to do it," Scales said. "If my nephew needs to ride those trains, I don't want anything to happen. I lost my son in '08. He got killed. So I know the power of not being able to do nothing. But I am going to stand up for what I believe. If I could help you, I'm going to do what I do."
