Authorities Investigate Possible Security Breach at Detroit Airport

A portion of a terminal at Detroit Metropolitan Airport was evacuated after authorities say a man walked through a passenger screening checkpoint and refused to comply with security officers.

The Transportation Security Administration says the passenger failed to stop about 7:45 a.m. Monday at the McNamara Terminal. Airport spokesman Mike Conway says the man was arrested by airport police and was being questioned.

Conway says the man's vehicle was located at the airport in suburban Detroit, and it was searched and towed.

Conway says security doors were lowered at the terminal between the security area and the concourse, and people in that area were evacuated. He says security screening resumed about an hour later.

People evacuated from the terminal were screened again.
