A drugs gang which kept 400 cannabis plants at a house in South Normanton have been jailed for a total of 22 years.
Police launched Operation Trevino after the discovery of a cannabis factory in a house on Victoria Street.
It came to light on November 15, 2011 after the owner of the house contacted police to say he had been refused entry to the property by the tenants.
When officers arrived they found the drugs growing under the watch a 35-year-old Vietnamese man, Tuan Ho.
That night a suspicious car, containing another four members of the gang, was stopped as it had driven past several times.
Text messages exchanged between the gang lead the force to swoop on a series of addresses in Nottinghamshire, West Mercia and the West Midlands -seizing 1,000 plants in total.
Last Friday, Thi Cuc Le, 43, was jailed for five years and four months, Hong Lam, 47, was sentenced to five years. Kieu Oanh Le, 32, and Hoai Nguyen, 43, were both jailed for 21 months.
Kirandeep Virk, who duped property owners into thinking he was a legitimate letting agent, received 18 months. Two other gang members, aged 17, were also jailed. They had all pleaded guilty to conspiracy to produce cannabis at an earlier hearing.
On sentencing, the judge said the growers were forced to live in ‘squalid conditions’.
Investigating officer Det Con Remi Hopkins, of Derbyshire police, said: “This was a long and complex investigation into a widespread organised group.”
“The excellent, co-ordinated investigations by police in four different counties have been critical to securing these convictions and sending a strong message to those involved in the supply of drugs that we will find you and bring you to justice.”
