Embarrassed Japanese customs officials were left red faced after it emerged one of their trained detection dogs had failed to detect a stash of drugs deliberately planted in a passenger’s luggage.

The customs agents were trying to train the dog ‘on the job’ at Narita airport and planted a 142 grams of cannabis into a random passenger’s suitcase with the aim of the dog detecting it as it ran through a detection check.

Unfortunately the dog failed to signal the drug and bumbling customs operatives forget which suitcase they planted the drugs in.

“The dog couldn’t find it and the officer forgot which bag he put it into,” a spokeswoman explained in Tokyo. “If by some chance passengers find it in their suitcase, we’re asking them to return it.”The cannabis is valued at about £5,000.

Ironically Japan has some of the toughest drug smuggling laws in the world.

A 38-year-old customs officer, suspected of planting the drugs, was acting against regulations according officials. Regulations require dogs be trained in a controlled environment for their drug detection work.”I knew that using passengers’ bags is prohibited,” the customs officer is quoted as saying, “I did it because I wanted to improve the sniffer dog’s abilities.

“The dogs have always been able to find it before.”
