Two people were arrested Thursday night on suspicion of arson after allegedly starting approximately 24 fires Thursday just outside Pismo Beach.
Investigators arrested Dominic Wefald, 18, of Arroyo Grande and a juvenile. Authorities declined to release the name and age of the minor.
The fires were started at 4 p.m. in an area north of Oak Park Boulevard, east of James Way, according to a Cal Fire news release.
The fires were extinguished and officials declined to say how they were started, the extent of damages, potential motives and whether additional suspects were involved.
The investigation is ongoing.
