A woman in St. Louis, Mo. was arrested this week after police said she was caught shoplifting and cooking a small amount of methamphetamine inside a Walmart, the St. Louis Post-Dispatch reports.
The chemical concoction was found inside a soda bottle in the woman's purse after a Walmart employee confronted her about stealing cosmetics from the store.
Later the store's security and police discovered a 20-ounce bottle containing the drug. The Walmart was then evacuated. No one was injured.
The trend of cooking small quantities of meth for personal use--referred to as "one-pot" batches-- is on the rise, the paper reports.
"There are lots of one-pot cooks," St. Louis County police Lt. Mark Cox told the paper. "But taking it into Walmart is very unusual."
