A Greenfield man has been arrested following an investigation of possible sex with underage girls. In September police were alerted of allegations that 21 year old Ricardo Isidro Najera was using social media to engage in sex with female minors less than 14-years-old. On Wednesday Najera was arrested and booked into Monterey County Jail on charges including possession of child pornograpy and sex with minors under 14 years old.
