A woman who helped a 63-year-old man smuggle cocaine with a street value of more than £1m through Norwich International Airport was yesterday found guilty by a jury.

Griet Amanda Onsea, 34, from Uganda, was arrested by customs officers after they found 17.6 kilos of the Class A drug in her luggage in July. She denied importing drugs at Norwich Crown Court. Harry Lee Lum, 63, of Berkely, California, America, had admitted the offence at an earlier hearing.

Judge Peter Jacobs, remanding Onsea in custody, said they would be sentenced together. He said: “It was an absolutely massive amount of drugs and one can imagine the effects. I see day by day the misery and even death caused by drugs.”

The cocaine was being carried in Onsea's luggage but she claimed it had been placed there by somebody else and she was not aware of it.

Julia Hopkins, prosecuting, said the couple had arrive at Norwich on a flight from Amsterdam. They had travelled from Uganda, via Kenya, over a one-month period.

The drugs were hidden in document folders which customs offices noticed had double thickness in the lining and were very heavy.

The couple will be sentenced in the New Year.
