A package of drugs and other contraband, valued at more than $21,000, was seized Monday morning at Matsqui Institution in Abbotsford.
It is believed that the package – containing marijuana, heroin and a digital scale — was lobbed onto the property, perhaps with a potato gun fired from a distance.
Police were notified and the investigation is continuing, said acting assistant warden Scott Verwold.
He said Correctional Service of Canada uses a number of tools to stop the flow of drugs into prisons, including ion scanners and drug dogs to search buildings, offenders and visitors.
As well, a toll-free tip line (1-866-780-3784) is set up for people to anonymously report illegal activities in federal jails, including drug use and trafficking.
