Police have seized an Ottawa restaurant and a Gatineau building that houses a bar as part of a joint police investigation into the proceeds of crime from an organized drug-trafficking network based in Ottawa, RCMP said in a news release Thursday.

The RCMP, Ontario Provincial Police and Ottawa Police Service worked together to identify the assets that belong to the Alkhalil organization as part of a two-year investigation dubbed Project Anarchy. The investigation led to nine arrests and the seizure of 10 vehicles, four firearms and 24.5 kilograms of cocaine with an estimated street value of more than $12 million, RCMP said.

Hisham Alkhalil, the alleged head of organization, is expected to return to court Feb. 8 for the continuation of his preliminary hearing for drug-related charges, RCMP said.

A property on Rossland Avenue in Ottawa, worth about $1.1 million, was seized in January 2014 as part of the case, RCMP said.

Seizing two other properties at 354 Olmstead St. in Ottawa and at 175 Promenade Du Portage in Gatineau — worth a combined $1.4 million — is meant to "further disrupt and dismantle this drug trafficking network financially and to prevent further acts of criminal activity," said Ronald Lauzon, the acting officer in charge of the RCMP detachment in Ottawa, said in a news release.

Ottawa police Insp. Mike Laviolette said that "taking away their financial gains is the true penalty for their crimes."
