ATLANTA (MCT) — Needles were found Sunday in sandwiches for passengers in business class on two Delta Air Lines flights from Amsterdam to Atlanta, one to Minneapolis and one to Seattle, prompting investigations by the FBI and authorities in the Netherlands.

One passenger on a flight to Minneapolis was injured, according to Delta, by an object in a sandwich “described as a sewing needle.” Local authorities, U.S. Customs and Border Protection agents and paramedics met the flight in Minneapolis, where the passenger refused medical treatment.
