New York ( CNN ) -- An `` all-clear '' was given at New York 's John F. Kennedy International Airport Wednesday night after a DHL cargo facility there was evacuated following the discovery of a suspicious package , authorities said . The package originated from Yemen -- the source of last week 's thwarted bomb plot -- said New York Police Department Deputy Commissioner Paul Browne . The package was an envelope containing a cell phone and paperwork , Browne said . Investigators said they were looking at a `` solid mass '' in the package at JFK that showed up on an X-ray and was inconsistent with what they had been told were documents in the package . The package was addressed to a New York destination , a law enforcement source said . `` The bomb squad was called in to check it out , '' the NYPD 's Browne said . `` It was cleared . '' The package was discovered at 6:30 p.m . ET Wednesday , an official said . FBI agents , Port Authority police and U.S. Customs and Border Protection had inspected the package `` out of an abundance of caution , '' New York FBI spokesman Rich Kolko said . `` All clear . DHL got their signals crossed , '' John Kelly , a spokesman for the Port Authority of New York and New Jersey , told CNN . `` All is well and over . '' A DHL spokeswoman , Beatrice Garcia , confirmed some information about the suspicious package but rejected the Port Authority 's statement about the delivery company getting its signals crossed . Senior law enforcement officials said the package was one of the more than a dozen packages from Yemen that investigators had been looking for since Friday . At least seven other packages from that batch have been cleared by U.S. officials . Earlier Wednesday , the head of the U.S. Transportation Security Administration visited Yemen , five days after authorities disrupted a plot to send bombs from the Middle Eastern nation to the United States , the federal agency announced . Homeland Security Secretary Janet Napolitano , meanwhile , talked about cargo screening with top representatives of global shipping companies including DHL , FedEx , TNT and UPS , her department said . She talked about `` enhanced screening '' after shipping companies apparently carried the bombs unawares . She pressed home the same message in a call to the head of the International Air Transport Association , Giovanni Bisignani , the department said . TSA Administrator John Pistole met with Yemeni government officials , including Deputy Prime Minister Rashad al-Alimi , representatives from the Directorate General of Civil Aviation and the Ministry of Interior , and U.S. ambassador Gerald Feierstein , the TSA said . Pistole also received briefings from TSA inspectors deployed to Yemen and toured a cargo facility in Sanaa , the nation 's capital . Yemen said Monday that it is tightening security at all of its airports . Authorities in the United Arab Emirates and Britain found two packages Friday with explosives that were destined for synagogues in Chicago , Illinois . The explosive found in the United Arab Emirates may have traveled on passenger planes to get there , airline officials said Sunday . Investigators in Yemen say they strongly suspect that Ibrahim Hasan al-Asiri , al Qaeda 's top bomb maker in the region , is behind the explosive devices sent in the parcels . U.S. authorities are said to be also looking at al-Asiri because the parcel bombs used the same explosive , PETN , as last year 's foiled underwear bomber , also linked to him . A 23-year-old Nigerian citizen , Umar Farouk AbdulMutallab , has been charged with trying to blow up a December 25 flight from the Netherlands to Detroit , Michigan , with an explosive that was partly sewn into his underwear . A Yemen-based branch of the al Qaeda terrorist network claimed responsibility for that attempt . After last week 's incident , the TSA and U.S. Customs and Border Protection took immediate steps to enhance measures for screening inbound cargo , including grounding packages originating from Yemen destined for the U.S. , the TSA said . The agencies also deployed a team of inspectors to assist the government of Yemen with its cargo screening procedures . The day before visiting Yemen , Pistole spoke to the International Air Transport Association conference in Frankfurt , Germany , met with international aviation security officials and signed an international security agreement with Germany , the TSA said .
