SAN DIEGO - A young military enlistee climbed over several fences -- including one topped by razor wire -- between Marine Corps Recruit Depot San Diego and Lindbergh Field Thursday and then ran across a runway before being arrested, authorities said.

San Diego Harbor Police officers detained the man, who is in his early 20s, near the airport's Southwest Airlines terminal just before 6:30 a.m., moments after he dashed across the tarmac towards Terminal 1, Gat 6, while clad in boxer shorts and a T-shirt, SDHP Sgt. Brad Hizer said.

Authorities said the man was seen trying to hide in an airport vehicle.

The recruit was bleeding from cuts inflicted by the jagged security wire, which also apparently had torn off his pants as he crawled over the second perimeter fence, Hizer said. He was turned over to Marine Corps officials, who took him to a hospital.

Authorities said the man triggered a motion detector after he jumped over a double fence and barbed wire at MCRD. It was unclear why the man decided to enter airport property, though recruits from the adjacent military training base periodically do so, apparently to "get away from boot camp," the sergeant said.

No flight disruptions were reported.

The recruit, whose name was withheld, had reported to MCRD on Monday, was undergoing initial processing and had yet to begin his military training, according to a statement from the base.

According to SDHP Lt. John Forsythe, the recruit was only identified as a 22-year-old man from the Northern California city of San Rafael.

Forsythe said the recruit's only comments when asked any questions were "Sir, yes sir" or "Sir, the private doesn't understand the question, sir."

According to Forsythe, the recruit was not under the influence of drugs but showed the effects of having been through a boot camp.

Forsythe noted similar incidents happened a lot in the 1980s and 1990s.
