On the night of March 23, unknown suspects set two fires in Orange Park and another fire near the 500 block of El Camino Real, according to police.
Working with a police school liaison and school officials, South San Francisco police detectives earlier this week were able to identify two 14-year-old suspects responsible for the arsons.
Police said that during interviews, both suspects also confessed to setting other fires dating back to 2010.
The teens were arrested and referred to Hillcrest where they are expected to face arson and conspiracy charges. Both were released to their parents.
