A man was wounded in a stabbing while riding the CTA Red Line train in the Loop late Thursday.
The 25-year-old told police he was arguing with another man on the train when the man produced a sharp object and “swung” it, stabbing him in the arm in the 200 block of South State Street about 11:20 p.m., according to Chicago police.
The victim was taken in fair condition at Northwestern Memorial Hospital.
The attacker ran away and nobody was in custody.
