Thirty sex offenders were contacted on Halloween night.
Two of those were taken to the Fresno County jail, arrested during a sweep by state parole agents.
It’s called 'Operation Boo’ and ensures sex offenders are not using Halloween to lure new victims.
State parole agents went to the homes of sex offenders to make sure they're following the rules on Halloween night.
One of the sex offenders told CBS47 what's expected of him.
“Don't go outside after five o'clock, do not open the door after five o'clock, and I don't have no candy in the house,” the sex offender said.
We were asked not to show the faces of these sex offenders.
Another told us he understands why the rules are in place.
“I don't blame them because there are a lot of them out there that don't follow those restrictions,” another sex offender told us.
There is a curfew from 5 p-m until 5 a-m...
Sex offenders have to be at home on Halloween night.
No decorations or anything that would entice trick-or-treaters to come to their door.
“We have sex offenders with history of child molestation and other crimes against children and we know this is an opportune night. On nights like tonight kids are going to them,” said State Parole Agent Ken Katz.
We didn't find any Halloween night violations.
But the parole agents did make an arrest - a sex offender on parole for child molestation. Marijuana was found in his car.
“I wasn't really thinking about it much, but now I'm in handcuffs so I guess I should have thought twice,” the arrested sex offender told us.
It's the second time in a month this sex offender has been taken to jail for marijuana possession and violating his parole.
“I got out and went to a program, which I'm currently in right now.”
“So you’re currently in a program, for?”
“For marijuana,” the arrested sex offender said.
