Staff at Warkworth Institution have seized more than $155,000 worth of contraband.
Correctional Service Canada says the seizures are related to two separate incidents, which occurred within 24 hours of each other at the medium security facility.
The seized items included tobacco, drugs, cell phones, and cell phone accessories.
The Correctional Service of Canada uses a number of tools to prevent drugs from entering its institutions including ion scanners and detector dogs to search buildings, personal property, inmates and visitors.
