Police in Gaston County say a barbecue restaurant was selling more than barbecue to some customers.
The owner of Smokey's BBQ Restaurant was arrested earlier this week on a variety of marijuana-related charges.
Thirty-nine-year-old Donnie Allen Wooten of the Gaston County town of Dallas was one of three people arrested Tuesday.
Police said the investigation started in November after an undercover agent bought 30 pounds of marijuana.
Wooten faces more than two dozen charges. Thirty-five-year-old Michael Gene Huffman of Dallas faces more than 50 charges. Twenty-nine-year-old Tausha Michelle Mixon of Dallas faces seven charges.
Police say they are looking for a fourth suspect.
It was not known if the suspects have attorneys.
