Four men have been jailed for a total of more than seven years for drugs offences relating to cannabis farms.

Police discovered drugs with a street value of nearly £24,000 being grown in a unit at Chapel Green Works, off Little Horton Lane, Little Horton, Bradford.

Tyler Walker, 30, of Nene Street, Canterbury, George Runciman, 32, of Leamington Drive, Apperley Bridge, Guy North, 30, of Exmouth Place, Undercliffe, John Wood, 40, of Centre Street, off Little Horton Lane, and Joanne Marshall, 33, of Farringdon Square, Bradford, appeared at Bradford Crown Court on Friday.

Prosecuting, Tom Storey said police were called to the works on September 15 after the owner of a stolen Mercedes tracked his vehicle to the address. When they arrived officers smelled cannabis and found 26 plants being grown in special tents using high powered lamps and fans. When they examined CCTV of the building, they saw Walker enter the building on one occasion with his young children.

Mr Storey said Walker, Runciman and Wood were involved with producing cannabis at the site while North was involved in street dealing.

On January 4, police were called to Farringdon Square where they discovered a separate cannabis farm in a family home shared by Runciman and Marshall.

They found electricity was being abstracted from the network to supply power for 20 mature cannabis plants in a bedroom. The couple’s daughter, now aged four, was also living at the house.

Walker pleaded guilty to production of cannabis and handling a stolen VW van. Defending, Ashok Khullar said Walker felt pressured into helping grow cannabis by his father-in-law and is now trying to put his drug use behind him. Recorder John Thackray sentenced him to 30 months in jail.

Runciman pleaded guilty to production of class B drugs and defence barrister Jayne Beckett said he had worked hard to turn his life around after a previous conviction. He was handed a 47 month prison sentence.

Wood was jailed for nine months after being found guilty of production of cannabis but the court heard he was “only involved for a relatively short period of time”.

North pleaded guilty to a charge of possession with intent to supply class B drugs. In mitigation, Vincent Blake Barnard said North is “on the cusp of turning his life around”. He was jailed for nine months.

Marshall pleaded guilty to abstraction of electricity and production of cannabis but “played a lesser role” and received a two-year suspended sentence.
