WASHINGTON - No explosives were found aboard a plane that landed in Washington Sunday after someone made a bomb threat at an airport ticket counter in Ohio, an FBI spokesman said.

Andrew Ames said no hazards were found aboard the plane that landed about 1 pm at Reagan National Airport. Authorities swept the plane for explosives including the luggage and interviewed the 44 passengers. The person who made the threat at the Dayton airport was taken into custody.

The threat shut down the airport for about 20 minutes. US Airways Flight 2596 was moved away from the gate after landing, the FBI said.

Airport operations were back to normal afternoon, although some US Airways flights were delayed because the affected flight was taken to an area used by the airline, Metropolitan Washington Airports Authority spokeswoman Courtney Mickalonis.

The plane was close to Reagan National at the time the threat was received, so officials allowed it to proceed to Washington, FBI spokesman Andrew Ames said.

All of the passengers got off safely.
