From the Associated Press:
A flight from the Taiwanese capital to the eastern Chinese city of Shanghai was diverted to a nearby Chinese airport Saturday after a passenger told cabin crew his luggage contained explosives… Chen identified the detained passenger as George Lin and said he was traveling on a U.S. passport. He said that Lin did not appear to have been drinking excessively.
“The passenger told the cabin crew very calmly that he had explosives in his luggage,” Chen said. “After the plane landed in Hangzhou, it was very carefully checked and nothing was found.”
Chen said the plane was on the ground in Hangzhou for about four hours before continuing onto Shanghai. It landed there without incident at around 5 p.m. (0900 GMT), he said.
