A person was stabbed on a CTA Blue Line train early Monday, according to Chicago police.
The incident took place just after 7 a.m. in the 400 block of South Racine Avenue, near the Racine El stop on Chicago's Near West Side, officials said.
Chicago police said a person suffered a superficial stab wound and was taken to Stroger Hospital. Information on the victim, including age and condition, was not immediately available.
The train was operating with single-track use for roughly 15 minutes due to police activity in the area, according to a spokesman for the CTA. The train returned to normal service just before 8 a.m. but was operating with residual delays, the agency said.
No one was in custody, according to police, and the investigation remains ongoing.
