Pennsylvania State Police are investigating an explosion in Crawford County Sunday.

It was reported in the 200 block of Railroad St. in Spartansburg Borough around 8 p.m.

Donald Smith, 56, at some point caused an explosion using an unknown gas or chemical reaction, according to troopers.

Several neighbors called State Police to report the noise and said Smith lit some type of fireworks or Tannerite in his backyard, which caused their houses to shake.

A shredded garbage bag was found on an adjacent property, troopers said.

State Police said Smith will be cited for disorderly conduct and scattering rubbish.
