About 150 police officers raided marijuana grow-ops across Seymour Arm, a remote community of about 70 people at the north end of Shuswap Lake, on Tuesday 5 October 2004.[1][2][3][4] Carrying 28 search warrants, officers searched 14 properties and seized more than 20,000 marijuana plants and about 50 weapons.[5][1][2][3][4]

Sixteen people were arrested and released with promises to appear in court; no one resisted the raids.[5][1][3][4] Police said the operation followed a two-year investigation opened after residents complained of violence, threats and intimidation by growers.[5][3][4]

The RCMP’s Combined Forces Special Enforcement Unit led the operation with help from neighbouring detachments, the Coordinated Marijuana Enforcement Team, Calgary police and sheriffs’ officers.[3][4] Officers found grow-ops in attics, basements, underground bunkers and outbuildings, including multi-level factory-style operations with nurseries and drying rooms, powered by commercial-grade generators.[5][3][4] Police said the marijuana was bound for Vancouver, Calgary and the United States, and described the growers as a tightly knit group running a sophisticated distribution network.[5][2][3]
