AMHERST, NY (WIVB) — A possible underground meth lab was discovered under a Walmart parking lot in New York Monday afternoon.

As Walmart shoppers ran their errands, two first responders in full hazmat suits were lowered beneath the parking lot through a man hole.

“It’s a concern I mean it’s unbelievable in this area, this isn’t a bad area,” said Steve Harding, who lives about two miles from the store.

Amherst Police told WIVB that officers found the evidence in a culvert that runs below the parking lot. They said it’s tall enough to stand up in and it was not secured, so anyone could access it.
