A man has been arrested after a woman was stabbed to death on a Chicago Transit Authority Red Line train Thursday afternoon in what police believe to be a domestic violence incident.
Police said a 25-year-old woman was stabbed in the neck on a train just after 12:30 p.m. in the 200 block of West 47th Street and was pronounced dead at the scene. A man was arrested as officers arrived at the scene, according to Chicago police spokesman Anthony Guglielmi.
According to authorities, a man and a woman were arguing on one of the trains and as the train approached 47th Street, the man stabbed the woman.
"This is domestic in nature, we're sure of that," said Chicago Police First Deputy Superintendent John Escalante. "There were other witnesses on the train with them who saw the argument."
Frantic passengers called 911 just moments after the stabbing.
"I had my headphones on," said witness Andrea Patterson. "He asked the young lady a question, she said no, and he got up and started stabbing her. She fell to the floor and he slit her neck."
An officer was nearby when the calls were placed and took the man into custody just minutes later.
"The details of the relationship we're still working on," Escalante said. "But it is apparent to the witnesses that were present that this was a domestic disturbance. There was some talk about a child."
Police said CTA surveillance likely captured the incident.
The CTA said service was suspended between 35th and Garfield due to police activity. Trains later began moving but were not stopping at 47th Street and were sharing a single track.
The identities of the man and woman have not yet been released.
