Two people were stabbed Thursday afternoon during an argument outside a CTA Brown Line station in the Ravenswood neighborhood on the North Side.
An 18-year-old woman and a 20-year-old man were stabbed after arguing with two other people at the station in the 4600 block of North Western, Chicago Police News Affairs Officer Thomas Sweeney said.
The man suffered multiple stab wounds in his upper body and was taken to Advocate Illinois Masonic Medical Center in critical condition, Sweeney said.
The woman, who was stabbed in the arm, was taken to Swedish Covenant Hospital, where her condition stabilized, Sweeney said.
The victims and the suspects apparently know each other, but no one is in custody Thursday evening, a police source said.
The man who was stabbed is affiliated with a gang, according to police.
