Acting Sgt. Sarah Swallow of the Delta police says in a news release that more than 50 municipal and RCMP officers executed four search warrants on homes in nearby Surrey and Langley on Thursday.
She says police seized a large amount of currency and illegal drugs.
Swallow says police will be recommending drug-related charges to Crown counsel.
More than 30 shootings believed to be related to a clash between two drug gangs have rocked Surrey and Delta in recent months.
The violence has prompted the federal government to promise 100 new Mounties for the area.
