Deputies patrolling the coastline saw the suspects unloading a panga boat at Montana De Oro State Park yesterday. Officials say deputies also spotted suspicious vehicles drive into the park just after midnight yesterday.
Deputies initiated a traffic stop on Los Osos Valley Road shortly after watching the men load drugs into four vehicles.
The suspects face federal drug smuggling charges and were booked into San Luis Obispo County Jail. The amount of drugs has not been released.
Homeland Security will take over and conduct further investigation.
