Asian gangs pose major threat, police report says | CBC News
Asian organized crime poses a major threat in Canada because it is widespread, sophisticated and highly influential, says a police report released Friday.
Insurance fraud, money laundering, human trafficking, street gangs and sexual exploitation of children are all raised as concerns in the annual report from the Criminal Intelligence Service Canada.
"Organized crime is a very, very serious threat to this country," said Chief Edgar MacLeod of the Cape Breton Regional Police.
Asian gangs are very active around Vancouver, Edmonton, Calgary and Toronto, said the organization, which includes the RCMP, provincial, regional and municipal police departments, and intelligence and regulatory agencies.
These gangs are considered a significant threat because of their number of sophisticated criminal operations, influence in many areas of the country, and supply of illicit drugs to other organized crime gangs.
