Security officials in Florida are investigating how a 27-year-old man managed to jump a fence at Tampa International Airport and run along a runway.
Two flights were delayed while the man was chased by police and arrested.
He was caught within three minutes of jumping the fence, airport spokeswoman Janet Zink told CNN.
The man, who has a history of mental illness, was given a warning and taken to hospital for evaluation.
The incident briefly delayed a Southwest flight from Tampa to Houston, and a United flight from Tampa to Chicago.
