Randy Bartosh, a former Columbiana resident, pleaded guilty to fraud this month after an investigation by the Ohio Bureau of Workers’ Compensation found he was collecting benefits while running a tattoo shop in Pennsylvania. Bartosh pleaded guilty Aug. 15 in the Franklin County Common Pleas Court after repaying more than $4,500 to the state. The BWC’s special-investigations department opened an investigation after a confidential source contacted the fraud hotline to say Bartosh was engaging in physical activity inconsistent with his complaints to doctors in his workers’ compensation claim.
