16 people have been arrested after cannabis worth almost €1.6 million was seized in raids across the north.
The searches took place in Armagh, Tyrone and Fermanagh over the past two days.
The PSNI says nine suspected cannabis factories were uncovered.
Eleven people have since been charged with a range of alleged drug offences.
Two people have been released on bail and two have been released unconditionally, with one person still in police custody.
