A Corner Brook household got a parcel that was intended for someone else, and found out that it contained a large amount of marijuana.
The Royal Newfoundland Constabulary said a courier service was used to deliver a parcel to a home in Corner Brook last Friday.
Police were called in because the parcel looked suspicious.
When it was opened, it was found to contain about 15 pounds, or about 7.2 kilograms, of weed.
The RNC's drug section is working with the force's forensic identification service to find the people connected to the parcel.
