(Richmond, IN)--A Richmond couple was taken into custody overnight and they now face multiple drug charges.  Joshua Smith and Katherine Potts were located in the 1200 block of North A.  They’re both charged with possessing controlled substances.  Potts’ arrest late Tuesday night came just hours after a pre-trial hearing was held earlier Tuesday in a case where she allegedly struck a highway department worker while she was driving under the influence of controlled substances.  That incident happened last May on U.S. 35 near Williamsburg.
