The fire office has put up pictures of the suspect taken by security cameras so that the public can help find the person.
In a statement, the fire bureau said that the first fire started around 3 a.m. Wednesday at the corner of Northeast 28th Avenue and Sandy Boulevard. In the hours that followed, around 10 fires were started in different parts of the city. The last one that was known to be started was in the inner Southeast part of Portland just after 7 a.m.
The fire bureau said that detectives working with accelerant-detection dogs found evidence at the fire scenes that led them to think that the fires were all started by the same person.
Lt. Jason Andersen can be reached at 503-823-378 by anyone with knowledge or security camera footage that might show relevant images.
