A woman is in critical condition after she was set on fire while riding the "L" train system in Chicago, police said.
Police said a person of interest was taken into custody in connection with the incident Tuesday. No details about the person were released.
The woman, 26, was riding a Chicago Transit Authority train on Monday night when she got into an argument with an approximately 45-year-old man, police said in a statement.
The verbal altercation turned physical when the man poured a liquid on the woman and ignited it, causing the woman to catch on fire, police said. It is not clear what liquid the man poured on the woman.
When the train stopped, the suspect fled the scene while the woman set aflame exited the train and fell to the ground, police said.
