ST. CATHARINES, Ont. – Seven people were arrested Thursday in Canada connection with a 14-month investigation into a large-scale international drug trafficking operation dubbed “Project INK,” Niagara Regional Police reported.

The arrests followed the announcements of five arrests in May. At that time, police had seized bout 110 kilograms of cocaine valued at more than $30 million along with $1.6 million cash, vehicles and more than $1 million worth of jewelry in the drug operation which involved the transportation of narcotics from Mexico.

Authorities said Thursday’s arrests, which included suspects from Kingston, Woodbridge, Niagara Falls and Niagara-on-the-Lake, Ont., as well as Vancouver, B.C., “shut down a significant pipeline used by Mexican drug cartels and their U.S.-based networks to distribute drugs throughout the United States, Canada and Europe which, in turn, then funneled the proceeds back to Mexico.”
