A man was seriously injured with burns after a house explosion took place in Summit early Sunday.
Officials responded to the incident around 7 a.m. Sunday near 60th Street and Harlem Avenue.
Surveillance videos from the Windy City Auto Spa and Mars Bar businesses nearby show the moment debris went flying from the home, and the home was soon engulfed in flames.
A few moments later, a man is seen walking away after having suffered burns to 30 percent of his body, according to firefighters.
Summit Fire Chief Wayne Hanson said the front and side walls had been "blown out" and one person, believed to be in his 40s or 50s, was transported to Loyola University Medical Center after being pulled out of the house with burns.
According to fire officials, it is believe that the house was unoccupied and that the man inside wasn't supposed to be there.
"He didn't belong in the building," Hnason said. "The building wasn't occupied by a tenant."
The incident is still under investigation and the cause of the incident is unknown. Foul play has not been ruled out according to investigators, but they also said that it could take weeks to figure out what happened to cause the explosion.
The owners of Windy City Auto Spa and Mars Bar gave surveillance video to authorities, and neither business was damaged by the explosion.
