Terminal B at Sacramento International Airport was shut down temporarily after five people got past an unattended security checkpoint.

The security breach happened Saturday when a walk-through metal detector was left unattended for less than a minute, officials said.

After noticing it was unattended, Transportation Security Administration officials closed the checkpoint and went to search for the five individuals that got by. Police were called to help.

"All five individuals were located and were brought back to the checkpoint and rescreened as a precaution," according to a statement from the TSA.
