HAMILTON, Texas (AP) – Almost two dozen people have been arrested after Central Texas authorities went undercover into a drug ring that included black tar heroin being sold from a small-town chicken restaurant drive-through window.

Hamilton is about 110 miles southwest of Fort Worth.

The Hamilton County Sheriff’s Office said Wednesday that 20 people have been arrested for felony delivery of a controlled substance.

And while serving warrants, officials also arrested three other people and charged them with possession of a controlled substance.

Sheriff’s officials said that the focus of the undercover operation began targeting methamphetamine suppliers in October 2016.

During the operation, they also discovered that black tar heroin was being sold from a now-closed Bush’s Chicken in Hamilton.
