VANCOUVER (AP) — Investigators say a fire that significantly damaged an apartment complex in Vancouver and sent people leaping out windows Saturday was arson.

The Columbian reports no serious injuries were reported in the fire that started Saturday evening. The Vancouver Fire Marshal's Office says about $250,000 in damage was done to four units.

The Vancouver Fire Marshal's Office said Tuesday the fire is believed to have been arson. Authorities are looking for a white woman in her 20s with light brown hair who may have been in the area driving a silver BMW X5 at the time.

Vancouver Fire Marshal Heidi Scarpelli says an award of up to $1,000 has been offered for information that leads to an arrest and conviction in the case.
