Meth lab found underneath a Walmart parking lot

We've heard countless stories about people brewing up meth in Walmart bathrooms, but now police have found a meth lab underneath a Walmart in Amherst, New York! They discovered the underground lab inside a culvert below the store's parking lot and a crew in hazmat gear is now clearing out the tunnel. From WIVB:

Well talk to the proper authorities to figure out what we need to do to make sure thats not accessible anymore, said Captain Scott Chamberlin.

He said they did not receive any tips. The culvert was checked during a random preventative patrol.

Routine patrol, thats what we do every day, said Captain Chamberlin.

We asked him if its routine to check underground.

He said, We check in various areas that people who might be up to no good, might be using for no good.

Members of the NYSP Contaminated Crime Scene Emergency Response Team passed buckets of evidence up from the manhole.

Spray paint can, some various chemicals, a liquid we believe is methamphetamine, said Captain Chamberlin.
