Felony charge filed against OC man who allegedly tried to have sex with 4-year-old

A felony complaint has been filed against the 29-year-old Orange County security guard accused of trying to pay to have sex with a 4-year-old girl.

The complaint charges Nicolas Ryan Castillo with solicitation to commit sexual assault and asks for bail of $100,000.

Castillo was arrested last week after authorities say he offered a woman - who turned out to be an undercover detective - $700 for sex with her child.

The arrest followed a month-long investigation involving Santa Ana police and the FBI. Investigators collected boxes of electronic evidence from his home and believe there may be evidence of child pornography.
