A large package of illegal drugs and contraband camouflaged with glued-on grass clippings has been intercepted by officers at a prison in Mission, B.C., according to Correctional Services Canada (CSC).

Inside was 300 grams of suspected methamphetamine, bottles of suspected steroids and other unidentified pills, razor blades and an iPhone in a sparkly case.

CSC puts the estimated value of the package contents inside the prison, where prices are much higher than on the outside, at $165,000.

Mission RCMP have opened an investigation. In a news release, Mounties say the package was possibly flown by drone over the fence of Mission Institution at night and dropped into the prison yard.

“The package was cleverly disguised by attaching real cut grass around the entire exterior of a bubble-mailer, helping it to seamlessly blend in with the grass inside the fenceline of the institution,” reads the release.

Guards found the package during morning rounds on April 8.
