A 45-year-old Oklahoma woman was arrested for allegedly trying to start a meth lab -- in a Walmart store.

Police were called to a Walmart in Tulsa, Okla., after store employees saw a woman start to take items used to make meth off the shelves, local news station KJRH reported. She then tried to make the drug while she was still in the store.

Staff called police, who arrived and took the items outside the store. Some of the chemicals spilled, and one officer suffered a minor burn to his hand.

Police say this isn't the first time this woman has been arrested on meth-making attempts.

"She's been arrested before for the manufacture of methamphetamine. While speaking with some of the firefighters on the scene she made statements that that's what she was doing that she was attempting to obtain these chemicals and was in the process of trying to manufacture methamphetamine. However she said that she was not very good at it," officer David Shelby told KJRH.
