A Wichita Falls man is behind bars tonight, charged with the alleged sexual assault of an eight-year-old girl.
Forty-year-old Robert Rios is charged with aggravated sexual assault.
Arrest records state the girl claims she woke up to Rios touching her in the middle of the night.
Authorities say Rios claimed he woke up and accidentally stumbled and fell on top of the victim.
But police say they don't believe that could have happened because of the layout of the home.
Rios is jailed on a $150-thousand bond.
