Officials examine suspicious packages in U.S., U.K.

PHILADELPHIA (AP) — A suspicious package in the United Kingdom has prompted searches of three UPS planes and a truck in the U.S.

New York City police say all the suspicious packages being examined in the U.S. came from Yemen. No explosives were reported to have been found.

During a security screening process in the United Kingdom today, officials found a suspicious item on a cargo plane, according to a U.S. government official who spoke on condition of anonymity to discuss the ongoing investigation.

U.K. 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.
