Police say they made their first sizable seizure in November at an apartment in the 45600 block of Brett Avenue in Chilliwack.
The Combined Forces Special Enforcement Unit said the arrests followed a seven-month long investigation into an alleged Chilliwack based drug distribution network.
Police seized more than $5 million in drugs and arrested seven people during raids in November 2014 and February 2015 according to CFSEU-B.C. spokesman Sgt. Lindsey Houghton.
More than $5 million in drugs were seized including cocaine, crystal meth, crystal MDMA, crack cocaine, powder cocaine, fentanyl in pill and powder form and 56 kilograms of phenacetin and 54 tubs of MSM used as cocaine buffing agents.
Fentanyl, a painkiller 100 times more potent than morphine, has recently been the subject of a number of warnings in B.C. after causing overdoses and death when mixed with other drugs.
The police raids also netted weapons, including three semi-automatic rifles, two sub-machine guns equipped with sound suppressors and a number of handguns and ammunition.
Police say the gang distributed the drugs in cities and towns in central and northern B.C. from Williams Lake to Fort St. John.
