Cannabis blunder at Tokyo airport

An unwitting passenger arriving at Japan's Narita airport has received 142g of cannabis after a customs test went awry, officials say.

A customs officer hid a package of the banned substance in a side pocket of a randomly chosen suitcase in order to test airport security.

Sniffer dogs failed to detect the cannabis and the officer could not remember which bag he had put it in.

Anyone finding the package has been asked to contact customs officials.

"This case was extremely regrettable. I would like to deeply apologise," said Narita International Airport's customs head Manpei Tanaka.
