Los Banos police arrest man, 20, in Kerman in sexual assault investigation involving minors

Los Banos police arrested a 20-year-old man in Kerman on Oct. 28 in a sexual assault investigation involving minors, the Los Banos Police Department said.

Rico Ray Herrera-Castillo was booked into the Fresno County Jail. Police listed four booking charges by penal code section, which cover rape, forcible sexual penetration of a minor, oral copulation with a minor and misdemeanor sexual battery.

The investigation began earlier this year after someone reported sexual assaults that had happened over several years, according to the department. Investigators identified victims and gathered evidence that led to several search warrants and an arrest warrant.

Investigators and officers from the department’s Special Services Unit went to Kerman on Oct. 28 to serve a search warrant at a home where they believed Herrera-Castillo was living. He was there and was taken into custody without incident, police said. Investigators seized several items of evidence.

An arrest doesn’t mean a person committed a crime. Herrera-Castillo is presumed innocent unless convicted.

What’s still unknown

The police announcement doesn’t say:

• How many victims there are or how old they are
• How Herrera-Castillo knew them, or where the assaults are alleged to have happened
• Whether prosecutors have filed charges, or when he is due in court
• His bail

The investigation is ongoing. Anyone with information is asked to call the Los Banos Police Department at 209-827-7070.
