Suspicious Packages Checked on 2 Cargo PlanesPosted: Updated:
WASHINGTON (AP) - Some airports are on high alert after investigators found a suspicious package aboard a plane flying from Yemen to Chicago when it stopped in London on Thursday night, a law enforcement source with detailed knowledge of the investigation said.
The suspicious package, which contained a "manipulated" toner cartridge, tested negative for explosive material, the source said, but it led to heightened inspection of arriving cargo flights in at least three cities -- Newark, New Jersey and Philadelphia, Pennsylvania and a UPS truck in New York.
Investigators were examining two UPS planes that landed at Philadelphia International Airport and another at Newark Liberty International Airport in Newark, New Jersey, said Mike Mangot, a UPS spokesman.
Authorities are focusing on flights coming from Yemen into the United States, according to the source.
The Transportation and Security Administration said authorities were acting "out of an abundance of caution."
"The planes were moved to a remote location where they are being met by law enforcement officials and swept," the administration said in a statement.
In Philadelphia, three people aboard one plane were removed from the plane and scanned with negative results, the Philadelphia Fire Department said. The type of material that may be involved is not known, officials said.
In Newark, investigators were examining another UPS plane, said Mike Mangot, a UPS spokesman.
And a bomb squad in New York City is responding to a report of a suspected explosive device inside a package aboard a UPS truck, the deputy police commissioner said.
UPS said it is cooperating with authorities, and its shipment is being removed from the aircraft.
