Eleven people reportedly went through an unmanned security checkpoint at New York’s JFK Airport on Monday morning, prompting authorities to scramble to make sure they didn’t pose a threat. Joe Pentangelo, a spokesman for Port Authority of New York and New Jersey, told the Associated Press the incident took place in Terminal 5, and that three of the individuals were identified and set to be screened upon their arrival in California. The remaining eight passengers were believed to have boarded various flights. The Transportation Security Administration released a statement after the incident confirming that a screening lane had been left open and unattended. Three passengers “did not receive required secondary screening after alarming the walk-through metal detector,” the statement said. The administration said the incident posed “minimal risk,” as the passengers’ luggage had been properly screened and a K9 unit present in the area had not detected anything amiss.
