EAU CLAIRE - An Eau Claire area doctor may have been using his profession to sexually assault teenage boys.

Police first arrested Dr. David Van de Loo in October.

A 16-year-old boy's parents claim Van de Loo had sexually assaulted their son during an examination at the Mayo Clinic Health System in Eau Claire.

Now, 13 other victims have come foward.

Van de Loo was in Eau Claire County court Tuesday facing additional sexual assault charges stemming from those claims.

He's currently out on a $50,000 cash bond.
