Flights were briefly disrupted at LaGuardia Airport in the United States, as New York City police arrested a man who they say threatened an airline employee with a bomb, Fox News reported Saturday.

The disruptions lasted about 90 minutes. Airport officials said the threat was determined to be "non-credible."

The man reportedly told the employee he was coming back with a bomb and then returned a short time later.

No explosive was found and the suspect was quickly taken into custody.
