The 11 key events that led to the downfall of the Khan family's organised crime group as police dismantled major drug conspiracy in south Leeds

Four members of the Khan family have been jailed for a total of more than 20 years over their 'ring and bring' cannabis supply operation.

The Khans' ran the illegal operation from their family home on Tempest Road, a property described by a judge as a 'drug supermarket'.

Officers executed search warrants at a number of homes in south Leeds and seized 3.5kg of cannabis.

Large amounts of cash and other drugs were also recovered from properties and vehicles during a dogged investigation which took almost 18 months.

Drugs seized by officers represented only the 'tip of the iceberg' in terms of the actual amount of cannabis thought to have been sold.

A phone line operated by the gang received 200 messages a day during the period of the conspiracy.

From the vast number of calls and messages received on phones belonging to gang members, officers were able to calculate that at least 40kg of cannabis was sold on the city's streets.

Brothers Asif and Kashif Khan and their cousins Shamrayz and Sohail were handed prison sentenced at Leeds Crown Court yesterday (February 12).

Prosecutors outlined the following 11 key events in which detectives were able to prove the family's involvement in a conspiracy in order to bring them to justice.

EVENT 1: October 4, 2017. Tempest Road.

Police went to the Tempest Road address following an anonymous call reporting an incident in which a male had been injured.
