More than 200 law enforcement agents from multiple agencies paid surprise visits to recently released prisoners on Tuesday.
Operation "Tip The Scale" targeted about a hundred former prisoners who live in North County communities from Carlsbad to Solana Beach.
Probation officers found at least two dozen who had violated the conditions of their release including a Cardiff man who had a jar full of marijuana in his home.
"A lot of these guys have a violent history even though they were released on less serious crimes, some of their priors were very violent,"said Supervising Probation officer Jason Druxman.
Drugs are also a big issue and that's why counselors were on hand at a command post in Encinitas to offer treatment options.
