A doctor who got “in over his head” after coming into contact with the Comancheros has been imprisoned for supplying garbage bags full of prescription medication to the bikie gang.

Dr John Ullman, who made over $1.5 million from his prescription drug dealing, had been accused of using his Brisbane clinic as a front to illegally sell benzodiazepines and steroids.
