A woman and her 8-year-old son escaped a suspicious fire at their Hayward home early this morning, a Hayward Fire Department spokesman said.
The one-alarm fire was reported at 3:59 a.m. at a three-bedroom apartment at 29163 Dixon St.
The mother and son were sleeping when the mother heard glass breaking, Hayward fire spokesman LaShon Earnest said.
She went into the living room and found a fire burning and saw that there was a roughly 12-inch hole in her front window, Earnest said.
When fire crews arrived, smoke and flames were coming from the apartment's windows. They opened up the roof to ventilate the blaze, and controlled the fire in six minutes, Earnest said.
The fire caused an estimated $100,000 in damage to the building and destroyed $25,000 in contents, he said.
The blaze is considered suspicious, in part because of how quickly the flames spread, Earnest said. He said investigators are looking into whether an object was thrown through the window.
No injuries were reported, and the American Red Cross has been called in to help set up the residents with temporary shelter.
