Denver, CO – The FBI screened passengers from a Delta Airlines flight from Detroit to Denver on Friday after a potential security threat.

“The majority of the Delta Flight 1500 passengers have been allowed to claim their luggage and continue with their travel plans,” FBI spokesman Dave S. Joly said.

A law enforcement official told CNN that a bomb threat found written on a note prompted the security screening after the plane landed at Denver International Airport.

The 737 aircraft, which was carrying 151 passengers and six crew members, landed safely at 4:40 p.m. MT as scheduled, said Russell Cason, a spokesman for Delta.

The plane was taken to a remote location at the airport for the screening.
