A jury heard how police launched an undercover drugs operation after a teenager's tragic death in a road accident.

Charleen Goodey, 18, died instantly when she was struck by a car on Halifax Road, Buttershaw, in April last year.

Yesterday a jury at Bradford Crown Court was told that police inquiries revealed that before her death Charleen, of Buttershaw Drive, Bradford, had been given a £5 wrap of amphetamine by a woman who later said she had bought it at a house in the Woodside area of the city.

Prosecutor David Dixon said an undercover police officer was sent to the house in Rosley Mount on two occasions last May and both times he was able to purchase wraps of amphetamine. Two women - Ellen Horn, 27, who had lived at that address for 11 years, and 30-year-old Paula Hudson, of Meadway, Woodside - have gone on trial accused of various drugs offences in relation to activities at the house.

The jury was told that a third woman, Michelle Dewhirst, who lived at Rosley Mount with Horn, has already admitted supplying amphetamine to the undercover officer and being concerned in a second supply of the Class B drug to him.

Horn has denied supplying the £5 wrap of amphetamine to a woman who passed it on to Charleen, known as Char to her friends.

She has also denied further charges of permitting her premises to be used for the supply of amphetamine between December 1998 and May last year, being concerned in the supply of the drug to the police officer, and possession of amphetamine.

Hudson has pleaded not guilty to supplying the amphetamine to the officer on his first visit to the house in May and supplying the drug on a day in December 1998.

Mr Dixon said after their arrests Horn initially denied knowing the woman supplied at all, but later admitted that she did.

She also said she was not aware of any drug dealing taking place at the house and was not involved in any herself.

Hudson also denied any involvement in drug-dealing.

Mr Dixon said when police searched the house they recovered a wrap of amphetamine from a bag of frozen chips in a freezer and two other wraps of the drug from behind the appliance.

They also searched the office of a car-valetting firm where the three women worked and a bag with traces of amphetamine was found in a desk drawer.

Mr Dixon stated that scientific tests showed the plastic bag containing the amphetamine supplied to the woman was strongly linked to the bag found in the office desk.

The trial continues.
