He was previously convicted in 2021 for the supply of cocaine and heroin.
His long criminal history also saw him go on the run for six years to evade detection following a previous investigation in 2013.
An international arrest warrant was issued, and he was arrested whilst travelling from Istanbul to Sweden.
When detained, police found he had two phones and £2,500 cash.
Det Insp James Coles said: “Din was fully aware of the illegalities of his actions but, regardless, he sought to profit from the trade of these highly destructive commodities.
“By removing Omar Din from the chain of command, we will have disrupted their operation, and we continue to identify those below him so we can dismantle the entire organised crime group.”
