Suspect Package Found On Plane In London, Plane Travelling From Yemen To Chicago | UK News | Sky News The first package was discovered on a United Parcel Service jet, which had stopped to refuel at East Midlands Airport in Derby while flying from Yemen to Chicago. It was apparently made from a converted ink toner cartridge, which contained white powder and had wires sticking out. The second was found on a plane in Dubai, which had also flown from Yemen and was on its way to the US. The American government is investigating whether the packages were a dry run for a mail bomb plot. US security sources said al Qaeda in the Arabian Peninsula (Aqap) would be at the top of the list of suspects if terrorism links are confirmed. Sky's crime correspondent Martin Brunt said the UK package was found on the plane at about 3.30am this morning after a tip-off. The package was checked and at some stage was given the all-clear because the plane was allowed to continue its flight to North America," he added. For some reason this package was revisited and then concern grew again - so much so that for the last 12 hours or so this police operation has continued. But this wasnt a package that was addressed to anybody in the UK. It wouldve stayed on the plane and carried on with the rest of the cargo to North America." Two United Parcel Service planes were searched at Philadelphia airport. One of them had flown in from Paris Another UPS plane at Newark airport in New Jersey was searched and given the all clear. Two vehicles in New York City were also investigated, as well as a package outside a court in Portland, Maine. Terrorism expert Neil Livingstone told Fox News: Clearly they probably had some intelligence that indicated there were going to be bombs placed on cargo planes and theyve been able to mobilise very quickly to deal with likely flights. The cargo hold has always been of great concern in cargo planes because weve never really got our arms around the security of those planes.
