Police activity disrupted the CTA Red Line after an incident at the Sox-35th Street station Thursday night. Trains were not running between the Roosevelt and 63rd Street stops as of 10 p.m. Shuttle buses were requested, the Chicago Transit Authority said.

As yellow tape took over the inside of that train car, police were seen taking pictures where several evidence markers were placed on the ground near the train doors.

Two people, including a 13-year-old boy, were wounded in a shooting on a CTA Red Line train on the South Side Thursday night, Chicago police said.
