The Boise Airport is back to normal operations after a bomb threat closed a portion of the building Tuesday.

Flights were still landing and departing, but about 200 passengers were held in the security screening area as police investigated, said airport spokeswoman Patti Miller.

The threat focused on the food court area of the airport, which Miller said police have cleared. But officers are still on scene making sure the rest of the airport is safe, Miller said.

The threat was called in to the airport about 2:30 p.m. The area reopened about 4:30 p.m. Miller said she could not provide further details about the call.
