SALEM, Ore. (AP) — Police say they have identified a 37-year-old man as the culprit who set several fires at Salem City Hall last month.

The fires, set early on Dec. 26, caused about $5,000 in damage. Police said Saturday they had identified the suspect as Scott David Henry, of Salem.

Henry is already in custody on unrelated charges at the Polk County Jail. Police said they expected him to be arraigned on second-degree arson, first-degree criminal mischief and second-degree theft charges related to the fires.

It was not immediately clear if he had a lawyer who could speak on his behalf.

The fires were started in the basement of the parking structure as well as near offices on the second level. Police said several fire extinguishers were stolen and discharged on the outer doors of the second-floor offices.

One of the fires set in the city hall space near Peace Plaza caused $5,000 in damage to an industrial service cable belonging to a construction firm working on renovations at the Salem Public Library.
