Homeless man causes security breach in San Diego airport

SAN DIEGO, Calif.

The suspect was able to walk through an alarmed but unguarded emergency door inside the terminal. He then blended into a line of passengers boarding a commuter plane on the tarmac. Only a final passenger count by flight attendants nabbed the suspect before take-off.

Police say the man has an extensive criminal history. He's been arrested and charged with trespassing.
