Authorities investigating an alleged prescription drug trafficking operation in central Ohio and an alleged cocaine ring in northwest Ohio have started arresting dozens of people indicted in the cases. Columbus police and Franklin County authorities announced Tuesday that 47 people have been indicted in an investigation into prescription pill trafficking. Authorities say the suspected ringleaders are among more than 30 who have been arrested. Investigators allege defendants traveled to Florida to get prescriptions, then filled them in other states and sold pills. Attorney General Mike DeWine and local investigators separately announced Tuesday that about two dozen people had been arrested and indicted on charges linked to a suspected cocaine ring in northwest Ohio. Those defendants are charged in Sandusky, Ottawa and Wood counties.
