An Abbots Langley man has been jailed for his part in a £13 million cocaine operation run by two drug lords who were in prison.

Zoltan Arva, 39, of Spur Close, was jailed for eight years after pleading guilty to conspiracy to supply cocaine.

He was part of a drugs gang run by Kevin Bell, 33, of HMP Springhill and Anthony Delima-Bey, 32, of West End Road, Ruislip, while they were coming to the end of their sentences in an Aylesbury prison.

Northamptonshire Police said Bell and Delima-Bey “re-established ties with their criminal associates” while on day release. Delima-Bey was sentenced to 22 years in prison.

Seven other people – including Arva – transported drugs from London and Hertfordshire to Northamptonshire.

Delima-Bey worked with Paul Pierson, of Ganymede Place, Hemel Hempstead and used Zoltan Arva as a courier to supply drugs to Kevin Bell and his two cousins James and Michael Bell, Warwick Cobley and Kevin’s girlfriend, Nicole Abrams.

Detectives arrested James Bell following a car chase. He was caught with 500g of cocaine with 78 per cent purity.

Zoltan Arva was also stopped in a separate car on the A45. A bag was seized from the boot of his car containing £21,020.

A search of Delima-Bey’s house in West End Road, Ruislip, revealed £14,300 in £50 notes, £4,980 in £10 and £20 notes, three Rolex watches with a combined estimated value of over £26,000.

A glass jar with £5 notes totalling £4,255 and two wraps containing 1.7g of cocaine with a 44 per cent purity were also found.

The search also revealed pieces of paper wrapped in cling film. The paper contained a tick list with names and numbers, believed to be a dealers list. There were high value amounts on the list with the largest value being £969,000.

Police drugs expert testimony revealed that the list referred to debts amounting to £13 million.

Pierson, 36, of Ganymede Place, Hemel Hempstead, and James Bell, aged 32, of Lark Rise, Northampton, pleaded guilty to conspiracy to supply cocaine.

Pierson was sentenced to ten years in prison and James Bell was jailed for four years.

Nicole Abrams, aged 28, of Windflower Place, Northampton pleaded not guilty to conspiracy to supply cocaine, but was found guilty by a jury.

She was sentenced to four years in prison.

Michael Bell, aged 34, of Chaucer House, Chaucer Street, Northampton, pleaded guilty to being concerned in the supply of cocaine. He was sentenced to two and a half years in prison.

Warwick Cobley, aged 46, of Northfields Close, Deanshanger, pleaded guilty to possession of cannabis, possession of cannabis with intent to supply and production of cannabis.

He pleaded not guilty to further charges of conspiracy to supply cocaine and possession of heroin, cocaine and cannabis with intent to supply. He was found guilty at trial and sentenced to 21 years in prison.

Blake Ross, aged 46, of Kingsfold, Bradville, Milton Keynes, pleaded guilty to possession of heroin, cocaine and cannabis with intent to supply. He was sentenced to seven years in prison.
