A woman slipped through a security checkpoint at Houston's Bush Intercontinental Airport today — causing a security scare.

Authorities later learned the woman apparently was trying to find a bathroom.

Officials closed the terminal, then re-screened all the passengers.

Authorities recognized the woman in the airport as the re-screening began about 15 minutes later and detained her for questioning.

A Transportation Security Administration spokesperson says the woman was a connecting passenger who left the secure area to find a restroom, turned around and went back up the exit lane.

The terminal where the security breach occurred is the hub for Continental Express.
