CHICAGO (CBS) — A man has been charged with stabbing a 50-year-old man on a CTA Red Line train Sunday morning just north of the Addison station in Wrigleyville.

About 8 a.m., the victim was traveling south on the train in the 900 block of West Addison Street when a 23-year-old passenger walked up to him unprovoked and menacingly waved a small knife before stabbing him in the left hip, causing a small laceration, according to Chicago Police.

When police arrived, the 23-year-old attempted to run away and was taken into custody following a short chase, police said.

Thomas Pierre, 23, of the West Town neighborhood, was charged with misdemeanor counts of battery and reckless conduct for the attack, police said.

The 50-year-old was treated at the scene by paramedics, but refused further medical attention, police said.
