(KTL:A) – A Missouri sheriff’s department issued a reminder to people this week after a social media ad led to an arrest: keep your drugs out of online photographs.

The sheriff was tipped off by an eagle-eyed citizen who noticed someone trying to sell a catalytic converter online had posted a picture Tuesday night that included a “large bag of meth and syringe” in the background, the Stone County Sheriff’s Office reported.

On Wednesday, detectives went to the man’s home and served a search warrant.

“You can imagine his surprise!!” Stone County Sheriff Doug Rader wrote in a Facebook post. “He still had 48 grams of meth and a pistol that he is forbidden to own! We have now provided him a new place to stay.”

A jail record indicated the 38-year-old man was arrested Wednesday afternoon and booked on suspicion of drug-related offenses.

Deputies said that Kertz wasn’t aware the photo showed the narcotics, according to television station KY3 in Springfield.

“Take note, if you are selling items on social media, make sure your drugs are not in the background!” Rader wrote on Facebook.

And for those interested in purchasing the catalytic converter: unfortunately the item is not currently for sale anymore, according to the Sheriff’s Office.
