A teenage boy was shot in the arm on the 6200 block of South Cottage Grove around 2 p.m. yesterday.

The 16-year-old boy checked himself into the University of Chicago Medical Center, according to Chicago Police Department (CPD) spokesperson Veejay Zala.

The boy told authorities he sustained the wound through a drive-by shooting, and the case is currently under investigation by CPD, Zala said.

The incident occurred on a Safe Passage route near John Fiske Elementary School, according to the Chicago Public Schools (CPS) website. Launched this fall as a partnership between CPS and CPD, the Safe Passage program aims to protect Chicago students walking to and from school with the help of hundreds of neon-vested trained workers and volunteers.

This shooting comes after a holiday weekend during which three people were killed and at least 20 were wounded in shootings and stabbings across the city, according to DNAinfo Chicago.
