From CBS Radio in Philadelphia:  “At this time, all indications are that this was a hoax and a pretty nasty trick was played on a passenger,” Chief Inspector Joseph Sullivan said.

CBS News is reporting that the hoax may be related to a love triangle between the briefly-detained passenger and a former girlfriend and her new boyfriend. CBS News says a possible dispute between the three may have led to the hoax phone call. According to CBS News, the former girlfriend and her new boyfriend wanted to make the man’s life miserable and placed the hoax call. It was not immediately known which one allegedly placed the phone call.

Police say the tip caller now faces federal charges.

Sources tell Eyewitness News, a male and female are now in federal custody undergoing questioning in connection to the incident.

The 69 passengers and five crew members aboard the plane were removed and screened. The plane was also screened and cleared after no explosives were found and passengers re-boarded the plane and left for Texas.

PHILADELPHIA (CBSDFW.COM/AP) – A US Air flight is back en route to Dallas after being delayed due to a security scare, according to the airline’s website. Philadelphia police say the security scare that prompted authorities to recall the airborne flight was the result of a hoax.

Chief Inspector Joe Sullivan says a man removed from US Airways Flight 1267 at Philadelphia International Airport is not a suspect and did nothing wrong.

Sullivan says police are treating the hoax seriously. He says, “This is no joke, this is no laughing matter.”

Sullivan says someone called police at the Philadelphia airport and named a passenger who was in possession of a dangerous substance. That prompted a flight en route to Dallas-Fort Worth International Airport to be recalled. The plane was searched by bomb technicians and cleared.

Sullivan says someone played “a pretty nasty trick” on the passenger.
