The Billings Bomb Squad was called in to look at a device the Transportation Security Administration found in a passenger's carry on bag. Police Chief Rich St. John said situations like this should not be taken lightly. "A bomb is a bomb until it's not," he said.

He said the bag in question appeared to have wires, a battery, and some other items. Nate Reaver was the next person in the security line when the device was found. "They ran it through a couple of times," he said. "Then they evacuated us."

Passengers were evacuated from the security area, but were allowed to stay at the airport. Chief St. John said the woman who owns the bag is being questioned and is cooperating. Reaver said she was obviously flustered.

"She was trying to think of everything in her bag," Reaver said. "She kept saying she had a reading lamp. She was obviously very upset." While officials tried to determine what was going on, dozens of passengers had to re-think their travel plans, as the planes they were booked on took off without them.

An officer in a bomb suit went into the building removed the device and took it to another location to examine it. Chief St. John said they're still not entirely sure what was in the bag, but it's better to be extra cautious.

"The system worked well," he said. "Anytime you can go home, it's a good thing." Officials remind passengers to reduce the clutter in their bags before traveling. Sometimes knowing what you have stuck in pockets and folders can save you time at the security line.
