Meth lab is suspected cause of explosion in government building

Though it's hard to imagine that anyone would go so far as to set up a meth lab inside a government building, it's appearing like that exact thing happened. Among the many things the show Breaking Bad taught viewers is that sometimes the best place to build a meth lab – and hide illicit activity in general – is in plain sight.

Though it's hard to imagine that anyone would go so far as to set up such an operation inside a government building, it appears that's exactly what happened.

Officials suspect methamphetamine production had something to do with the July 18th explosion at National Institute of Standards and Technology in Gaithersburg, Maryland.

Check out pics from the time someone built a meth lab in Walmart:

The blast occurred in an unused room located within a small building designated for special projects.

Investigators reported that they turned up evidence consistent with meth manufacturing.

Thankfully, the incident occurred on a Saturday and there weren't many people near the explosion site at that time.

A security guard did, however, sustain injuries that required treatment.

That individual resigned from his job the next day.

Congress has shown great concern about how such an operation managed to get set up and function inside a government facility.

Law enforcement agencies are currently investigating the matter.
