Indiana State Police said an “active meth lab” was found after Wal-Mart employees reported a suspicious backpack in the men’s rest room.

Troopers had to wear protective respirators and suits to dismantle the lab and remove the chemicals.

Nobody expects to find a meth lab in a public place, but officials say they were not surprised.

"With warm weather approaching and outside activities increasing, so does the potential for people to encounter toxic and hazardous meth trash or a working meth lab left unattended," according to an alert from Indiana State Police in Pendleton, IN.
