A Bradford man, alleged to be a professional criminal, has been found guilty of conspiring to supply cannabis.

Terence Wilcock, 46, was accused of being involved in the establishment of a cannabis factory in the West Midlands and being the principal organiser when 26kg of cannabis valued at £100,000 was moved to the north to be distributed on the streets.

Wilcock, of Westgate Hill Street, Tong, pleaded not guilty to charges of conspiracy to produce cannabis between March and June last year and conspiracy to supply cannabis between August and September of 2007.

He was convicted at Leeds Crown Court, by a jury of six women and five men, of conspiracy to supply after a six-week trial. But the jury is still considering its verdict on the conspiracy to produce charge.

Wilcock was one of six men on trial, including David Romani, 47, of Beacon Brow, Buttershaw, who denies conspiracy to produce cannabis, and 47-year-old Lee Lupton, of Jarrom Close, Cutler Heights, who pleaded not guilty to conspiracy to supply.

The court had heard that another Bradford man, Richard (Dickie) Daniels, 38, of Beechwood Road, Wibsey, had pleaded guilty to the conspiracy and was also claimed to be a principal organiser.

Prosecutor Richard Wright told the jury that Wilcock was a professional criminal and the controlling force in the separate drugs conspiracies.

He said a cannabis factory had been set up in Walsall at commercial premises owned by another defendant, Chananjit Singh Mahal, 61, of Walsall. He had denied conspiracy to produce cannabis but was found guilty.

Mr Wright said electric cabling had been installed at the factory, lighting suspended from ceilings and the walls were lined with silver foil. When police raided it they found 1,000 cannabis plants, compost, water butts and chemicals. Mr Wright said it had been a “professional criminal enterprise”.

He alleged Romani was implicated in the conspiracy to produce and grow cannabis and had demonstrated how to mix chemicals for growing.

The prosecutor said police had observed the defendants and intercepted the consignment of drugs as it was being driven north. He alleged Lupton had been recruited by Wilcock as “muscle” to protect him in the course of his illegal business dealings.

Wilcock denied any involvement in the conspiracy. He admitted he had visited the Walsall factory but told the jury it was to buy clothing and to discuss buying the building.

Two other men from the West Midlands, Joseph Dupre, 67, and Jaswinder Tinsa, 43, deny conspiracy to supply.

After failing to reach further verdicts the jury was sent home and will continue its deliberations on Monday.

Wilcock and Mahal were remanded in custody. The other defendants were granted bail.
