THE last member of a £5.5 million drugs conspiracy gang that stockpiled 30 kilos of heroin at a Bradford flat has been sentenced to ten years' imprisonment.

Masood Aslam, 27, who was caught when drugs squad officers found a dealer list under his mattress, went on to courier cocaine while on bail.

Yesterday, he was jailed for six years and five months for his role in a drugs plot uncovered on February 12, 2013, when police raided a flat in Lister Court, Cunliffe Road, Manningham.

At the time, Aslam was on prison licence after being locked up for five years for possession of a handgun.

His latest sentence runs consecutively with a three year and seven month jail stretch he received at Manchester Crown Court last month for ferrying cocaine while on bail.

Prosecutor Tom Storey told the court that 30 kilos of heroin were seized from the flat in Bradford, along with a kilo of crack cocaine and 38 kilos of cutting agents.

The high purity of the heroin gave the haul a potential street value of more than £5 million.

Aslam, of Knightsbridge Walk, Holme Wood, Bradford, pleaded guilty to conspiracy to supply Class A drugs, between January and June, 2013.

He was arrested on August 22, 2013 when police found a dealer list under his mattress that was a copy of one seized from the Lister Court drugs den.

He told interviewing officers it was found in "purely innocent circumstances" and refused to answer any more questions.

While on police bail, in November, 2013, Aslam was stopped in a car that was transporting cocaine between Manchester and Bradford. He admitted possession of the drug with intent to supply.

In September last year, six members of the Lister Court gang were jailed for a total of more than 60 years at Bradford Crown Court for conspiracy to supply class A drugs.

Mr Storey said they included Aslam's brother, Mohammed Dawood Aslam, 36, also of Knightsbridge Walk. He was described as "the directing hand" in the plot and jailed for 17 years.

Police used camera surveillance at the flat to identify the men and tracked them using mobile phone activity as drugs were transported from Manchester to Bradford.

Jailing the gang members last year, Judge Peter Benson said: "In my view, this was the most substantial quantity of drugs to unleash on the streets of West Yorkshire, including a very, very substantial amount of heroin."

Masood Aslam's barrister, Khadim Al’Hassan, said his client had been in custody since January last year.

He was a drug addict from a young age, beginning with Class B drugs and going on to Class A.

His addiction had caused him kidney problems and his nose had to be rebuilt after it collapsed from so much drug taking.

Aslam had a wife and child to return to and was being rehabilitated in prison.

Judge Benson told Aslam, who was nicknamed Max: "You were trusted to copy a dealer list which indicates your knowledge of the extent of the conspiracy and the fact that you were trusted."

Aslam, who stood in the dock with head bowed and hands clasped, had taken "meaningful steps" to address his addiction, helping fellow prisoners to seek similar help, Judge Benson noted.
