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.
