Washoe County Sheriff's Deputies say they arrested a Sparks man last week on three child sex-related charges. 

Deputies say the charges are related to incidents that involved two female victims and occurred between 2013 and 2015. Both victims were known to the suspect, 42-year-old Harold Shawn Bias. 

Bias was arrested last Thursday on one count of Sexual Assault with a Child Under 14 and two counts of Lewdness with a Child Under 14.

This is an ongoing investigation although Detectives do not believe there are additional victims at this time.
