Sewing needles found in turkey sandwiches served in-flight has provoked a full scale investigation involving the FBI.
The needles were found in six sandwiches on four Delta Airlines flights on Sunday. The sandwiches had been prepared by an international catering company in Amsterdam.
One passenger was injured, but declined medical attention. Once the discovery had been made, the airline stopped serving the sandwiches and changed to pizza instead. A call was also made to other flights from Amsterdam to warn of the situation. The needles were found on flights from Amsterdam, Atlanta and Seattle.
Delta said security for its meal production has been increased and it is using more pre-packaged food while the investigation continues.
