The incident was reported shortly after 11:30 a.m., an official in the airport's flight tower told ABC7.
Aerial video from AIR7 HD showed the man standing along on the tarmac as an officer in an SUV approached him. The officer exited his vehicle and took the man into custody without incident.
The airport was subsequently reopened and all flights were resuming as scheduled, an official said.
It was not immediately clear how the man was able to breach security and gain access to the restricted area.
