Arson investigators called to fire at Scottsdale elementary

The Chicago Police Bomb and Arson Unit is investigating a small fire at a Scottsdale neighborhood elementary school that was extinguished before classes started Wednesday morning on the Southwest Side.

A custodian doing a routine building check smelled smoke and found the fire about 7:45 a.m. in the mobile unit of Stevenson Elementary School, 8010 S. Kostner Ave., according to Chicago Police and Chicago Public Schools spokesman Michael Passman.

Fire crews put out the blaze soon thereafter. No one was hurt, authorities said.

The mobile unit is used mostly for after-school programs and by a community group, so class were not interrupted, Passman said.

“Based on the preliminary investigation, there is no indication that there was a mechanical or electrical failure in any of the building’s systems,” according to a CPS statement.
