A Dublin man who worked as a counselor for at-risk minors and children with special needs has been arrested. 

According to Dublin Police Services, Nobumasa Masubuchi was the focus of a months-old child pornography investigation launched by the department. 

“During the course of the investigation, it was discovered Masubuchi possessed a multitude of CSAM (Child Sexual Abuse Material), depicting victims of sexual assaults possibly as young as four years of age,” DPS wrote.

The 23-year-old man was arrested on Friday and was booked into Santa Rita Jail in Alameda County for felony child pornography possession charges.

Masabuchi was a counselor for a Sacramento facility that assisted youth with special needs and conducted regular home visits with at-risk minors.
