London police and fire department investigators are looking into a reported arson at 144 Adelaide St. N., near Hamilton Road.
The fire was started on the outside of the home around 9:15 p.m. Friday evening.
Tina Doxtator says she was passing by and noticed the flames at the back of the house.
Her boyfriend, Melvin Albert, attempted putting out the fire, at one point getting an extinguisher from a nearby convenience store.
At the same time, Doxtator alerted four people inside home.
Albert said someone used gas to start the fire as there were gas cans at the back of the house.
The man said there were kids next door so he decided to try to put the fire out.
“My wife was freaking out. She wanted me to get away from there.”
He said he had no idea why someone would set the house on fire.
Witnesses say one woman from the house appeared to suffer mild smoke inhalation, but didn't require hospital treatment. There were no other reported injuries.
Police say they are looking for two suspects.
