TOKYO, Japan (CNN) -- China's main airline suspended several flights from Japan Friday after receiving a bomb threat purportedly aimed at disrupting the opening of the Beijing Olympics, Japanese transport officials said.
The email said the threat targeting Air China flights was intended to disrupt the Games which start Friday, according to Transport Ministry official Fumio Yasukawa.
An Air China flight with 61 passengers and 10 crew returned to Chubu Centair International Airport near Nagoya after the threat was received, an airport official told CNN.
The aircraft was searched, but no bomb was found.
The threat delayed four other Air China flights.
