Robert Greterman, 45, was arrested for an alleged attempted rape, assault with a deadly weapon and child molestation on June 21 at about noon on the 8600 block of C Avenue.

The victim's mother was notified at work, and the victim's brother reported that he confronted Greterman while the man was sitting in a chair holding the gun in his lap.


The victim was not injured.
