Authorities in Arizona said they arrested seven people on drug charges after a man on parole mistakenly texted a parole office employee for a drug deal.

The Mohave County Sheriff's Office said the Mohave Area General Narcotics Enforcement Team was contacted by the Arizona Department of Corrections Parole Office after parolee Christopher Willmon, 46, sent an apparent wrong-number text to a department official seeking to sell heroin.

It was unclear whether Willmon had texted his own parole officer with the offer.

The narcotics enforcement team arranged to make a purchase from Willmon, and he was found at the agreed-upon time Tuesday hiding in a shed with the heroin he was allegedly planning to sell.
