The FBI and police at Amsterdam's Schiphol Airport have opened a criminal investigation into how needles got into turkey sandwiches served to passengers on Delta Air Lines flights from Amsterdam to the United States.
Delta said what appear to be sewing needles were found in five sandwiches on Sunday. One passenger on a flight to Minneapolis was injured. The other needles were on two flights to Atlanta and one to Seattle.
Airport police spokesman Robert van Kapel said: "We are keeping all options open because at this moment we have no idea why somebody or something put needles inside the sandwiches so that is what we have to investigate."
