Authorities say Ronald Littlefield, 53, of Norco was arrested and booked into the Robert Presley Detention Center for multiple counts of related charges.
An investigation began after deputies responded to a residence in the 3700 block of Alhambra Street in reference to a recent child molestation investigation.
Investigators say they have since determined that Littlefield sexually molested two children over a period of several years.
Littlefield is being held on $3 million bail.
Anyone with information regarding this incident was urged to contact Detective Gonzales or Detective Hernandez at the Jurupa Valley Station at (951) 955-2600.
