Detectives are hunting an alleged gang boss after raiding a drugs factory where £500,000 of cocaine and ketamine were seized.
Images of Leon Dore, 36, are being circulated after the operation on May 5 this year. West Yorkshire Police say Dore, from Chapeltown in Leeds, also has links to Liverpool and Birmingham.
The drugs factory was discovered after a warrant was executed at a farm in Horsforth, Leeds, by the force's Serious and Organised Crime unit. A search of the site, believed to have been used for processing and packaging drugs, uncovered 10kg of cocaine and 20kg of ketamine with a total estimated street value of more than half a million pounds.
