INDIANAPOLIS (WISH) — Multiple people were displaced but no one was injured after a fire broke out Thursday afternoon at a south side apartment complex.

Indianapolis Fire Department was called just before 5:10 p.m. Thursday to the 100 block of Stephanie Lane. That’s at the Country Club Apartments off Pennsylvania Street just south of East Troy Avenue.

IFD says 11 units were affected by the fire, smoke and water. Investigators say utilities were shut off for the whole building.

A Facebook post from the fire department says the apartment management indicated a resident placed a mattress too close to a baseboard heater.

Despite breaching the attic space, the blaze was brought under control in 30 minutes.
