Clarksdale cardiologist and Coahoma County Supervisor Dr. Roger Weiner has been arrested as part of a federal investigation alleging he used an online chat room to hire out-of-state prostitutes.

According to a court affidavit, Weiner was arrested by FBI agents at a gas station just north of Clarksdale Sunday. He was transferred to the Bolivar County Jail, and on Monday appeared for a preliminary hearing before U.S. Magistrate Judge David Sanders.

Weiner was released Monday afternoon on $20,000 bond, and will reappear in Greenville on Thursday for a probable cause hearing.

Authorities say Weiner is alleged with violating the Mann Act, a federal statute which among its provisions, prohibits the solicitation of prostitution across state lines.
