PHOENIX -- Investigators are trying to determine if an apartment fire in Phoenix was set on purpose.

RAW: Woman arrested, fire scene

Crews were called out to a four-plex at 42nd and Van Buren streets at about noon Saturday.

While everybody did get out safely, the four units were destroyed.

A neighbor said she and her husband went outside after hearing a blast.

"We walked out our door and the apartment right across from us was on fire," Sandra Donaldson said.

Police arrested a woman who was running from the scene.

Investigators are questioning that woman.
