The Monroe Regional Airport was closed for several hours today after a bomb threat note was found in an on-board bathroom on during an American Eagle flight from Dallas.

Investigators found no bomb on the plane.

There were 15 passengers on the flight with three crew members.  FBI spokeswoman Mary Beth Romig tells KEEL News all 18 have been interviewed, but no arrests have been made.

American Airlines, which operates American Eagle, spokesman Matt Miller said the Embraer 140 left Dallas-Fort Worth International Airport at approximately 9:20 a.m. and landed in Monroe about an hour later.

Flights into Monroe were diverted to Jackson, Mississippi during the closure.
