A hearing into whether a Keighley woman can keep her £400,000 assets is to be heard in the High Court.

A judge will decide whether on the balance of probabilities Rosalind Glover's assets had been acquired as a result of her brother's multi-million-pound drug dealing empire.

It will be the first case of its kind held by the Assets Recovery Agency, set up by the Government to ensure people do not profit from crime.

Her assets have already been frozen by the High Court following an application by the agency, while the investigation is held.

The Property Freezing Order relates to land at Mark House Lane, Gargrave, near Skipton, and the proceeds of a sale of property in Keighley and other investments.

The total value of the assets frozen stands at £390,704.

Miss Glover's brother Matthew Glover, 43, was sentenced at Preston Crown Court in March 2002 to 25 years in jail.

He had supplied ecstacy, amphetamines and cannabis resin with a street value of £1.6 million.

Julie Davis of the Assets Recovery Agency said the investigation was likely to take some considerable time. It was being held as a civil hearing because it was not a criminal case and there could be no criminal confiscation.

Miss Glover's brother Matthew Glover, of Cliviger, near Burnley, was the head of a criminal organisation called The Firm.

His drug activities and that of his ten associates were unearthed during a huge police operation.

They were sentenced to a total of 101 years in prison.

In January 2003, Glover appeared at Manchester Crown Court ,where an order was made that he had benefited from drugs trafficking in the amount of £3 million.

A confiscation order was also made for £370,000 that included his house.

National crime Squad officers suspected others of assisting Glover to "launder" his drugs money and so continued their investigation.
