LITTLE ROCK, Ark. — The FBI wants law officers assigned to areas around the Mississippi River bridges at Memphis, Tennessee, to help keep an eye on the spans after a vague threat came in warning of an attack.
FBI spokesmen said Tuesday the threat was unsubstantiated but that local police were still notified.
Two cross-country routes traverse the Mississippi River at Memphis - Interstates 40 and 55. They remained open. Television station WHBQ in Memphis said an FBI advisory it obtained cited “potential danger” to the I-55 span from an Islamic State cell in Memphis.
Highway officials reviewed plans for rerouting traffic.
The Arkansas Department of Emergency Management said the threat had not reached a level requiring it to put anyone on stand-by. Spokesman Rick Fahr said threats that include specifics are rare.
