“According to FBI spokesman Tom Simon, the passenger’s luggage contained what appeared to be a modified pressure cooker, which was discovered through standard Transportation Security Administration screening. The passenger was detained for questioning but was not placed under arrest, Simon said. The pressure cooker and some of the contents of the luggage were seized by the FBI for analysis. Simon today declined further comment, and did not respond to a question from Big Island Now as to whether pressure cookers are now among the items prohibited from being carried on board airlines, either in carry-on or checked baggage.”
