Firefighters are watching out for hot spots after a massive fire destroyed a strip mall on Chicago’s north side.
The fire broke out Friday afternoon in the 3100 block of West Peterson Avenue.
Officials say it was likely started by roofers who were using torches.
The fire quickly consumed several businesses, forcing crews to attack the fire from the outside, because it was too dangerous to go in. The roofs of at least two buildings collapsed.
At one point, there were a series of explosions likely caused by propane tanks left on the roof by the workers. Chicago Police are now trying to track down that crew, which fled the scene after the fire broke out.
It took more than 200 firefighters over two hours to get the fire under control.
No one was hurt, but several businesses were destroyed.
