The case of a man arrested by campus police at Clemson in the investigation of credit card crime has spread to the nearby jurisdiction of Seneca. The Seneca police have announced they have added to charges already filed against Richard Clayton Sr. The 43-year old Clayton was arrested last week by Clemson campus police and charged with felony financial transaction card theft, petty larceny, and trespassing after notice. After a campus officer contacted the Seneca Police Department, that department filed similar charges, alleging Clayton took credit cards belonging to a university employee and coming to Seneca to use those cards. Clayton was being held Friday in the Oconee Detention Center.
