Forty officers launched a series of co-ordinated raids across the Island targeting suspected paedophiles, drug dealers and thieves.
Officers smashed down doors and seized equipment as they searched nine properties in the biggest series of raids seen in Jersey for years.
The operation began at 6.30 am when a convoy of police vehicles rolled out of police headquarters in Rouge Bouillon.
And just two hours later, five people were in custody on suspicion of downloading indecent images of children, with another facing questioning for cultivating cannabis and another for possessing drugs.
The police said this afternoon that ten arrests had been made.
