If you’re looking to sell hard drugs, you might want to avoid that most public of platforms, Craigslist.

Three men from Jefferson Parish, Louisiana (just outside New Orleans) were arrested Thursday after allegedly posting a Craigslist ad for heroin, and then trying to deliver the product, WWL-TV reported.

The reason they were arrested: It was a police officer, not a junkie, that responded to the ad.

Police were made aware Wednesday of the Craigslist ad, entitled, “take a ride on H train d@pe – $100,” WWL reported. The ad’s description reportedly read, ”Take a ride on H train, dog food, d@pe serious inquiries only!”

As “dog food” is apparently slang for heroin, police contacted the poster and arranged to buy three bags worth, WWL reported.

At the arranged time and place Thursday, police said a car pulled up containing Geral Bowman, 24; Avion Nelson, 24; Michael Zeringue, 32, and an awful lot of heroin.

Bowman reportedly got out of the car and delivered three grams of heroin before being chased and arrested, and when Nelson and Zeringue tried to escape in their vehicle, police quickly tracked them down and arrested them as well, WWL reported.

According to police, the vehicle contained more of the tan, powdery substance believed to be heroin as well as drug paraphernalia and firearms.

All three men now face a slew of drug distribution and other charges, WWL reported.
