Excerpts from the ChicagoTribune.com:
Orland Park police said a juvenile was charged with aggravated arson after allegedly starting a fire shortly after 5:30 p.m. Sunday inside the Old Navy store at Orland Park Place shopping center. About 50 customers and 13 store employees were evacuated without injury after the fire began on a merchandise display wall near the rear of the store.
Security camera video showed someone lighting the display on fire and an Orland Park police officer recalled seeing someone fitting the description standing outside the store watching. The suspect was apprehended a few blocks away.
