At approximately 1:30 a.m. Friday morning, Placentia PD responded to an elementary school for a burglary in progress. Two juvenile suspects were detained, and Anaheim air units were requested to locate two other juvenile suspects. The other two suspects were quickly apprehended, and all four suspects were caught with school property on their persons. The four had broken into a shipping container filled with school products. It is unknown if the juveniles are affiliated with the school in any way. Placentia PD will be handling the investigation.
