Two inmates in Indiana are accused of running a drug enterprise out of prison with the help of cellphones smuggled in by guards, the Associated Press reports.

The pair, Oscar Perez and Justin Addler, who are housed at different prisons, sold methamphetamine and heroin to inmates, according to a federal indictment that charges 40 people.

Unsealed Wednesday, the indictment accuses corrections officer Jon Dobbins of possessing meth and delivering at least one phone to an inmate.

In one cell phone call, Addler guided a woman through a drug deal of 20 grams of heroin at a truck stop, the AP reported.
