PHILADELPHIA — A suspicious package containing a toner cartridge with wires and powder was found during routine screening of cargo in the United Kingdom, prompting authorities to scour three planes and a truck in the United States on Friday.
Searches were also conducted in the northeastern cities of Philadelphia, Newark, New Jersey, and New York City.
UK officials discovered that a toner cartridge on the plane had been manipulated and found wires attached to it and white powder. Tests on the device came back negative for explosives, according to a law enforcement official who also spoke on condition of anonymity to discuss the investigation.
Concerns about the possibility of similar and potentially dangerous devices shipped elsewhere prompted officials to check other cargo headed to the US.
US Transportation Security Administration spokeswoman Kristin Lee says the planes in Philadelphia and Newark were being swept. The planes were moved away from terminal buildings so law enforcement officials could investigate.
The Philadelphia jet belonged to UPS. A source with knowledge of the situation who was not authorized to speak said officials in Newark were examining a UPS package.
In New York City, police responded to reports of a possible explosive in a UPS truck, top NYPD spokesman Paul Browne said. Browne said the package was removed and was being examined in Brooklyn.
