According to the Lacey Police Department (LPD), detectives identified and arrested the girl for probable cause with the help of a Thurston County Sheriff’s Office school resource officer.

Authorities say the 12-year-old was also booked on additional charges of second-degree assault, and unlawful imprisonment of another child. According to the LPD, these two charges stem from incidents that happened on the same day near the location of the fire.

Authorities say detectives will continue to work with the Lacey Fire Department on the fire investigation. 

On Wednesday, the Lacey Fire Department said it could be a "multi-day event" as they work to put the fire out.

This is a developing story.
