Cocaine, vehicles and thousands of dollars in cash have been seized after a lengthy investigation into an alleged scheme to distribute the drug in Saskatoon and rural communities in Saskatchewan.

Charges have also been laid against four men following Project Folsom -- a seven-month probe that involved the RCMP and municipal police across Saskatchewan, as well as in Calgary and Vancouver.

Police say the investigation included the execution of four search warrants at residences in Saskatoon between October and earlier this month.

An additional search was done at a residence in Vancouver, British Columbia.

Christopher Chu, Joshua Hoeber, Christopher Pang and Bennet Tse face charges ranging from trafficking in cocaine to possession of the proceeds of crime.

The suspects, who range in age from 23 to 31, will make court appearances in Saskatoon over the next few weeks and police say further charges may be laid.
