Operation Denver was initiated by the Regional Task Force when it was identified that the heads of several organised crime groups had joined forces in order to obtain and source controlled drugs between themselves.  These complex arrangements were investigated by Tarian specialist officers and enforcement activity and arrests took place in October 2010 and February 2011.

Nine persons were arrested for conspiracy to supply 1kg of Heroin and 5.5kgs of Cocaine.  The street value of the drugs recovered totalled £295,000 and £13,500 in cash was recovered.
