ROCKFORD (WREX) – The Rockford Fire Department said multiple fires at an apartment complex early Saturday morning were intentionally started.

Fire officials said crews were first called to a possible apartment fire in the 2300 block of Canary Dr. around 3:20 a.m. Saturday.

First responders found a fire burning on the outside balcony on the third floor. The building, according to RFD, is a three-story apartment for 12 families.

Firefighters immediately began to battle the blaze and evacuate people from the building.

Shortly after, a second fire was reported in the building next door in the 2200 block of Canary Dr. As other crews arrived on the scene, they discovered that multiple fires had been started in both separate buildings.

According to RFD, “several” fires broke out on the 3rd floor of the second building and were quickly extinguished as firefighters evacuated the building. No one was injured in either building.

Investigators say the fires have been determined to be “incendiary” in nature, but the investigation remains open and ongoing. The damage caused by the fires is estimated at $6,000.

RFD encourages anyone with information about the fires to contact Rockford Area Crime Stoppers at (815) 963-7867 or RFD’s non-emergency number at (779) 348-7171.
