TSA Investigating Security Breach At DFW Airport

US Transportation Security Administration officials are investigating how a man was able to pass through a security checkpoint without a ticket at Dallas/Fort Worth Airport and board a commercial flight.

The 26-year-old man parked his vehicle near an airport terminal entrance on Sunday night, walked through a TSA screening area and boarded the plane, the airport said in a statement.

The airport statement did not identify the man or the airline involved in the incident.

An airline agent discovered what happened before the flight departed and called airport police, who arrested the man on criminal trespass charges, the airport said. Officers searched the suspect's vehicle and "found no threat," it said.

TSA spokesman Mike England said the agency is working with the airport to evaluate passenger security checkpoints.

"Immediately following this incident, TSA made adjustments to the DFW screening area, has added more barriers, and is working to identify other long-term solutions that may require physical adjustments to the area," he said.
