Police say they've seized a large amount of illicit drugs headed for Victoria including a quarter kilogram of fentanyl – enough to potentially kill 125,000 people.

Two men were arrested early Nov. 30 after they took a ferry from the Lower Mainland and were heading toward downtown Victoria, according to police.

In addition to the fentanyl, police discovered the men were also carrying 100 grams of cocaine.

The arrests were the result of an investigation that lasted several weeks, police said, adding the drugs were likely intended to circulate in downtown Victoria.

Both men have known gang affiliations and remain in custody. Police say they're recommending charges against them related to drug trafficking.
