A man named Nicolas Castillo, 29, was arrested at his fiancé’s home, near a home on the 2200 block of Woodley Avenue in Anaheim, by the SAPD today, after an informant told police officials that Castillo was looking to have sex with any 4-year-old, according to KTLA.

Santa Ana police and FBI officials served search warrants at the Woodley Avenue home, and another home in Yorba Linda that is also associated with Castillo and is across the street from Bryant Ranch Elementary School, according to ABC.

Castillo allegedly claimed he molested children in the past and he wanted to talk with the mother of the 4-year-old girl – but he had no idea he was talking to an SAPD police detective who was posing as a mom while exchanging emails and text messages with the suspect, according to the O.C. Register.

Castillo allegedly told the detective that he was willing to pay up to $700 for two separate meetings with the fictional 4-year-old girl or $500 to spend a night with the child, according to the SAPD.

There may be more victims as Castillo lived next door to a daycare center in Anaheim named Appletree Preschool.
