An American Airlines flight made an emergency landing at an airport in Knoxville in Tennessee following a bomb scare, the media reported on Wednesday.

A spokesperson for McGhee-Tyson Airport in Alcoa, Tennessee, said the pilots on Tuesday night sought permission to land and urged the airport emergency crews be on standby, CBC news reported.

American Airlines spokesperson Ross Feinstein said Flight 1804 was bound from Charlotte to Indianapolis when the carrier got a bomb threat.

The airline told CBS News the "threat" came from a non-credible robocall.
 

After the plane landed, passengers were evacuated and the crew found no bomb or technical problem with the plane.

According to a witness, two people were removed separately from other passengers on the plane.

They were later seen by other passengers in the hotel they were staying in after being questioned by authorities and released.
